SUMMARY:Helen Barton Lecture: "Constructing Features from Data: Geometry\, Dimension\, Reduction\, and Invariants"
DESCRIPTION:This talk explores how to construct meaningful features from noisy\, high-dimensional data by leveraging geometric and invariant structures. First\, we introduce a geometric framework for dimension reduction using a power-weighted path metric\, which effectively de-noises high-dimensional data while preserving its intrinsic geometric structure. This framework is particularly useful for analyzing single-cell RNA data and for multi-manifold clustering\, and we provide theoretical guarantees for the convergence of the associated graph Laplacian operators.  \n\n\n\nWe then turn to the problem of constructing features invariant to group actions in the multi-reference alignment (MRA) data model. In this setting one has many noisy observation of a hidden signal corrupted by both a group action(s) and additive noise\, and one wants to recover the hidden signal from the noisy data. By formulating MRA in function space\, we uncover a new connection to deconvolution: the hidden signal can be recovered from second-order Fourier statistics via an approach analogous to Kotlarski’s identity. We extend this identity to general dimensions\, analyze recovery in the presence of vanishing Fourier transforms\, and validate the resulting deconvolution framework with both theoretical guarantees and numerical experiments. \n\n\n\n\n\nVirtual Lecture on Teams\n\n\n\n\n\nAbout the Speaker\n\n\n\nAnna Little is an Assistant Professor of Mathematics at the University of Utah and a core member of the Utah Center for Data Science and AI. She received a PhD in mathematics from Duke University in 2011 and was an Assistant Professor of Mathematics at Jacksonville University from 2012-2017\, a primarily undergraduate liberal arts institution. \n\n\n\nMotivated by a desire to focus more of her professional energy on research\, she left Jacksonville University in 2018 to complete a research postdoc at Michigan State University. After completing her postdoc\, she began a tenure-track position at the University of Utah in 2021. She has been the principal investigator on multiple grants from the National Science Foundation\, including an NSF CAREER award in 2025. Her research interests include geometric and graph-based methods forhigh-dimensional data analysis and signal processing with group invariant features.

SUMMARY:Helen Barton Lecture: The Math and Politics of Counting People
DESCRIPTION:Professor Moon Duchin\, University of Chicago \n\n\n\nTitle: The Math and Politics of Counting People \n\n\n\nAbstract: The Census is our most fundamental tool for measuring who lives in the United States\, and where. Ever since the founding of the country\, the categories have reflected how Americans think about ourselves\, and the data gets used for everything from funding allocations to political districting. So\, it might be surprising that the most recent Decennial Census included intentional injections of random numbers to noise the data for privacy protection. This was hugely controversial! In this talk\, Moon Duchin will explain some of the history and the impacts of how we enumerate the country. \n\n\n\nMoon Duchin is a Professor of Computer Science and Data Science at the University of Chicago. Her background in pure math centers on geometry\, topology\, groups\, and dynamics; her applied work uses these tools to build algorithms and models to study the mechanisms of democracy. She runs a multidisciplinary lab bringing math and computing into conversation with law\, policy\, and geography. Duchin has served as an expert In numerous voting rights court cases around the country\, and she is the co-editor of the volume Political Geometry. She is also an external faculty member at the Santa Fe Institute\, which is dedicated to the study of complex systems. Duchin is a Fellow of the American Mathematical Society.

SUMMARY:Helen Barton Lecture: "Real Numerical Algebraic Geometry and Applications"
DESCRIPTION:Professor Jonathan Hauenstein\, University of Notre Dame \n\n\n\nTitle: Real Numerical Algebraic Geometry and Applications \n\n\n\nAbstract: Nonlinear polynomial equations naturally arise throughout mathematics\, science\, and engineering with their solutions describing various phenomena including the motion of a mechanical linkage such as a robotic arm and steady states of a dynamical system arising from a biochemical reaction network. Polynomials are central to some of the deepest mathematics and have been studied for millennia. The advent of modern computers has ushered in a new wave of algorithms for computing solution sets to systems of polynomial equations\, both from an algebraic and geometric perspective. Since the physically-meaningful solutions in most applications are real\, this talk will highlight recent developments for numerical computing and representing real solutions to systems of polynomial equations\, collectively called real numerical algebraic geometry\, along with demonstrating them on several applications in science and engineering.

SUMMARY:Helen Barton Lecture: "Optimal Transport and Topological Data Analysis for single-cell biology"
DESCRIPTION:Professor Zixuan Cang\, North Carolina State University \n\n\n\nTitle: “Optimal Transport and Topological Data Analysis for single-cell biology” \n\n\n\nAbstract: Single-cell and spatial transcriptomics data examines high-throughput gene expression profiles at fine resolutions providing an unprecedented opportunity to elucidate the underlying complex biological processes. Optimal transport and Topological Data Analysis has proven to be an effective tool for exploiting complex structures in high-dimensional data. In this talk\, we will discuss several optimal transport variants motivated by the biological applications\, where there are detailed application-specific constraints\, multiple distribution species\, and multiple embedding spaces of the same system. We will illustrate the applications of these tools for addressing multi-compatible molecular species in cell-cell communication analysis and devising coherent trajectories of the same biological system from multi-omics datasets. We will also discuss some applications of topological data analysis to single-cell data analysis.

SUMMARY:ANTCoG seminar: Talia Fernós
DESCRIPTION:Talia Fernós\, Visiting Professor at Vanderbilt University and Professor in the Department of Mathematics at University of North Carolina\, Greensboro (on leave) \n\n\n\n \n\n\n\nTitle: The semi-simple theory of acylindricity in higher-rank \n\n\n\nAbstract:  \n\n\n\nAcylindricity may be viewed as a generalization of being a uniform lattice in a locally compact second countable group. The recent surge of results concerning acylindrical actions on hyperbolic spaces demonstrates the utility of the property. Trees are of course examples of hyperbolic spaces\, and by considering products\, we start to see new and interesting behaviors that are not present in rank-1\, such as the simple Burger-Mozes-Wise lattices\, or Bestvina-Brady kernels.  \n\n\n\nIn a joint worth with S. Balasubramanya we introduce a new class of nonpositively curved groups. Viewing the theory of S-arithmetic semi-simple lattices as inspiration\, we extend the theory of acylindricity to higher rank and consider finite products of delta-hyperbolic spaces. The category is closed under products\, subgroups\, and finite index over-groups. Weakening acylindricity to AU-acylindricity (i.e. acylindricity of Ambiguous Uniformity) the theory captures all S-arithmetic semi-simple lattices with rank-1 factors\, acylindrically hyperbolic groups\, colorable HHGs\, and many others.  \n\n\n\nIn this talk\, we will discuss the Tits’ alternative and deduce that a group G that admits an (unbounded) AU-acylindrical action on such a product is “semi-simple” from the point of Out(G)\, thereby giving a partial resolution to a recent conjecture by Sela.

SUMMARY:ANTCoG seminar talk
DESCRIPTION:Our speaker will be Andrew Stout from CUNY. \n\n\n\nTitle: Computations of generalized jet schemes in SINGULAR using the arc.lib library \n\n\n\nAbstract:  \n\n\n\nJet spaces associated to an algebraic variety are important in the area of singularity theory. In this talk\, we will give an introduction to this particular area of algebraic geometry with the goal of offering an accessible introduction to research in this area.  We will discuss how to write down the equations of a jet space and why having the ability to compute these equations directly in a computer algebra system is important in the first place. Then\, we will use the speaker’s new SINGULAR library arc.lib to perform some exploratory calculations. If time permits\, we will also discuss some of the more theoretical results of the speaker related to jet schemes and some open questions amenable to experimental exploration via the arc.lib library.  \n\n\n\n*Support for this project was also provided in-part by a BMCC-CUNY Faculty Development Grant entitled \n\n\n\n“Singularity Theory\, the Rogers-Ramanujan Identities\, and the Cohen-Macaulayness of Jet Schemes.”

SUMMARY:ANTCoG seminar talk
DESCRIPTION:There will be an ANTCoG seminar talk on Friday September 5th in Petty 150 at 4pm. Our speaker will be Thomas Weighill from UNCG. \n\n\n\nTitle: How to map data to the circle (or anything else) \n\n\n\nAbstract:  \n\n\n\nA common challenge in data analysis is to reduce a high-dimensional dataset to a low-dimensional approximation that can be visualized. In some recent work with Ranthony Clark and Tom Needham that started life as a redistricting project\, we came up with our own method for mapping data onto a circle that suited our needs. The method ended up performing well in more general contexts as well. I’ll talk about the application we had in mind\, introduce the method\, and show some results.

SUMMARY:ANTCog - Phousawanh Peaungvongpakdy (Washington State University)
DESCRIPTION:Title: Case Studies of Short Burst Optimization for Multiple Redistricting Criteria  \n\n\n\nAbstract:  \n\n\n\nIn complex and non-convex energy landscapes like those that occur in the discrete context of partition sampling for redistricting\, optimal states can be difficult to discover. In 2023 Cannon et al. demonstrated that “short bursts’’\, biased random walks performed in a small number of steps and repeated\, led to significantly better performance than simple biased walks in finding global optima in this redistricting context. In this talk\, we will present case studies applying short bursts to a variety of traditional redistricting criteria. Applying this method on real-world redistricting data allows us to explore tradeoffs between metrics and the corresponding Pareto frontiers. We also present some results about short bursts on simple random walks on labeled graphs.

SUMMARY:Helen Barton Lecture: "Integral Tales: Some Unexpected Connections"
DESCRIPTION:Victor H. Moll is a professor of mathematics at Tulane University. \n\n\n\nDuring the process of learning calculus one observes that there is a well-defined list of rules to compute derivatives: product\, quotient\, and chain rules are among the first taught in every class. On the other hand\, when one tries to compute integrals\, the student is left with a feeling that now there is simply a collection of tricks. There is no clear reason why one can integrate ex in a simple manner\, but the integral of ex^2 is more complicated. One learns these tricks from the instructor\, by talking to older classmates\, or by searching for them online. At the end\, there seems to be no systematic way of doing this. \n\n\n\nIt is remarkable that\, in the search of producing closed-forms of definite integrals\, one finds many interesting connections with apparently disjoint parts of mathematics. Examples will include (1) properties of a collection of positive integers appearing in the evaluation of a rational function\, (2) a planar dynamical system connected with a variation of the arithmetic geometric mean and (3) a list of definite integrals involving the gamma function. The lecture will be suitable for undergraduates and it will include stories about how the speaker got involved in such projects.

SUMMARY:Colloquium
DESCRIPTION:Reception at 3:30 p.m. in Petty 116\n\n\n\nNicolò ZavaInstitute of Science and Technology Austria (ISTA)\n\n\n\n4:00 p.m. – 5:00 p.m. in Petty 219\n\n\n\n“An introduction to the role of the Gromov-Hausdorffdistance in computational topology”\n\n\n\nComputational topology is a well-established field at the crossover of topology and computational geometry. It aims to transfer the power of topology for quantitative analysis to the setting of discrete approximations\, typically finite data sets sampled from underlying objects. This analysis is usually performed by computing invariants of the spaces that extract patterns and features. The most important tool developed in this theory is persistent homology\, summarized by persistence diagrams. Successful applications of these invariants to real-world datasets started a whole new field known as topological data analysis (TDA). Given the ubiquity of data in our modern world and their importance in data-driven science\, a more interpretable\, geometry-based approach to treating large amounts of data is crucial. \n\n\n\nThe Gromov-Hausdorff distance is a notion of dissimilarity between metric spaces introduced by Gromov to study the convergence of metric structures. Earlier notions can be found in Edward’s and Kadets’ works. In the past decade\, it found applications in computational topology\, where it provides a theoretical framework to shape recognition and dataset comparison. Studying the metric properties of this distance helps us understand the advantages and limits of specific invariants. Using notions from dimension theory\, we can quantify the unavoidable loss of information. \n\n\n\n\n\nColloquium Event Flier with Nicolò Zava \n\n\n\n\n\nThe first part of this presentation introduces computational topology and TDA\, presenting some basic concepts and ideas. Then\, we discuss the Gromov-Hausdorff distance and its role in computational topology. Finally\, we present some results exploiting metric geometry and dimension theory to show theoretical limits to the precision of invariants\, bridging pure and applied mathematics.

SUMMARY:Ant-cog Seminar
DESCRIPTION:The ANT-CoG (Algebra\, Number theory\, Topology\, Combinatorics\, & Geometry) seminar will meet Friday\, 2/28\, from 4:00-5:00pm in Petty 150. We are pleased to welcome our own Dr. Thomas Weighill for Friday’s talk. \n\n\n\nTitle:  {vectorize\, data?\, unordered\, (continued)\, Can\, you} \n\n\n\nAbstract: In this talk we will continue to examine the question of whether vectorizations which introduce a bounded amount of distortion (i.e. coarse embeddings) exist for certain data types. It turns out that this question is also important in other fields such as geometric group theory and the topology of manifolds. I will touch on some known results about the space of probability distributions and the space of persistence diagrams. I will then present a recent result of my own on spaces of finite samples\, and quotients of spaces by finite group actions. This talk will be a thematic continuation of the previous one\, though it should be understandable even if you missed the first talk.

SUMMARY:ANT-CoG Seminar Talk
DESCRIPTION:The ANT-CoG (Algebra\, Number theory\, Topology\, Combinatorics\, & Geometry) seminar will meet Friday\, 2/21\, from 4:00-5:00pm in Petty 150. We are pleased to welcome our own Dr. Thomas Weighill for Friday’s talk. \n\n\n\nTitle:  {vectorize\, data?\, unordered\, Can\, you} \n\n\n\nAbstract: We will look at some very theoretical results motivated by the practical problem of visualizing and vectorizing complex datasets like shapes\, samples\, densities\, and even Congressional district maps. We will talk about some general strategies that sometimes work\, and prove at least one impossibility result showing that in some cases no good vectorizations exist. This talk will be designed to be accessible to undergraduate and graduate students.

SUMMARY:Colloquium: "Restoring Confidence in the Value of Mathematics"
DESCRIPTION:with guest speaker Travis Jarvis from Brigham Young University\n\n\n\n\n\nJoin the Department of Mathematics and Statistics for this free colloquium presentation\, open to the public. Located in the Petty Science Building\, Room 150. \n\n\n\nAbstract: Fifteen years ago\, math majors at BYU told us\, “We love math\, but we know it won’t get us a job unless we want to teach.” This feedback motivated us to create the ACME program—a curriculum designed to teach mathematics that is not only deep and beautiful but also practical and in high demand by employers. \n\n\n\nSince its inception 11 years ago\, the ACME program has doubled the number of math majors at BYU. Our graduates command higher starting salaries and gain admission to top graduate programs\, flourishing in both academia and industry. In this lecture\, I will share the challenges we faced in launching ACME\, the factors behind its success\, and the lessons learned along the way.

SUMMARY:Helen Barton Lecture Series: The Mathematics of Doodling
DESCRIPTION:Doodling is a creative and fundamentally human activity\, resulting in doodles iwth intricate and often hidden implicit structure. We will treat doodles as an example for how mathematics is done – by starting with some doodles\, we will ask ourselves some natural questions and see where they take us. They will lead us to some unexpected places\, and to some sophisticated mathematics. \n\n\n\nSpeaker: Professor Ravi VakilRobert Grimmett Professor of Mathematics at Stanford University President of the American Mathematical Society (February 1\, 2025)https://math.stanford.edu/~vakil/
