#### Well-rounded forms and the Voronoi tessellation

One identifies the space of binary quadratic forms with the upper half plane $$\mathfrak{h}$$. The set of well-rounded forms corresponds to an…

#### Hermite Constants for Real Quadratic Fields

The Hermite constant for the ring of integers in real quadratic fields $$\mathbb{Q}(\sqrt{d})$$ for square-free positive integers $$d$$ are plotted above. The…

#### Extensions of the $$p$$-adic field $$\mathbb{Q}_p$$ with Galois group $$E_1$$

Let $$p$$ be an odd prime number. The graph shows the subgroup lattice of the group $$E_1$$, which is the unique non-abelian…

#### Involve — a journal of mathematics

The mathematics journal Involve is dedicated to showcasing and encouraging high quality mathematical research involving students (at all levels). The editorial board consists of…

#### Riemann zeta Function $$\zeta$$ and its Derivative $$\zeta’$$

The absolute value of the Riemann zeta function $$\zeta(\sigma+it)$$ for $$0 \le \sigma \le 8$$ and $$0.1 \le t \le 60$$ over…

#### Zeros and Zero-Free Regions of $$\zeta^{(38)}$$

The plot shows the distribution of the zeros of the 38th derivative of the Riemann zeta function on the complex plane with…

#### Zeros of the derivatives of the Riemann zeta function

The plot shows zeros k of the derivatives $$\zeta^{(k)}(\sigma+it)$$ of the Riemann Zeta functionon the complex plane. In 1965 Spira had already…

#### Zeros of the derivatives of the Riemann zeta function on the left half plane

The plot shows zeros k of the derivatives $$\zeta^{(k)}(\sigma+it)$$ of the Riemann Zeta function the complex plane. For a table of zeros…
