  • Moon Duchin

    Helen Barton Lecture: The Math and Politics of Counting People

    Helen Barton Lecture Series
    Petty Science Building Room 150 317 College Ave, Greensboro, North Carolina

    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.

    Helen Barton Lecture: “Real Numerical Algebraic Geometry and Applications”

    Helen Barton Lecture Series
    Petty Science Building Room 150 317 College Ave, Greensboro, North Carolina

    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.

  • Zixuan Cang

    Helen Barton Lecture: “Optimal Transport and Topological Data Analysis for single-cell biology”

    Helen Barton Lecture Series
    Petty Science Building Room 150 317 College Ave, Greensboro, North Carolina

    Professor Zixuan Cang, North Carolina State University Title: "Optimal Transport and Topological Data Analysis for single-cell biology" Abstract: 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... Continue reading...

  • ANTCoG seminar talk

    Petty Science Building Room 150 317 College Ave, Greensboro, North Carolina

    Our speaker will be Andrew Stout from CUNY. Title: Computations of generalized jet schemes in SINGULAR using the arc.lib library Abstract:  Jet 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... Continue reading...

  • ANTCog – Phousawanh Peaungvongpakdy (Washington State University)

    Petty Science Building Room 150 317 College Ave, Greensboro, North Carolina

    Title: Case Studies of Short Burst Optimization for Multiple Redistricting Criteria  Abstract:  In 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... Continue reading...
