Tate's isogeny theorem

In mathematics, Tate's isogeny theorem, proved by Tate, states that two abelian varieties over a finite field are isogeneous if and only if their Tate modules are isomorphic (as Galois representations). (Wikipedia).

Joe Neeman: Gaussian isoperimetry and related topics II

The Gaussian isoperimetric inequality gives a sharp lower bound on the Gaussian surface area of any set in terms of its Gaussian measure. Its dimension-independent nature makes it a powerful tool for proving concentration inequalities in high dimensions. We will explore several consequence

Graph Theory: 09. Graph Isomorphisms

In this video I provide the definition of what it means for two graphs to be isomorphic. I illustrate this with two isomorphic graphs by giving an isomorphism between them, and conclude by discussing what it means for a mapping to be a bijection. An introduction to Graph Theory by Dr. Sar

Taylor Dupuy (Nov. 13, 2020): Abelian Varieties Over Finite Fields in the LMFDB

I will talk about things around the LMFDB database of isogeny classes of abelian varieties over finite fields (and maybe even about isomorphism classes). These could include: --"Sato-Ain't" distributions, --weird Tate classes, --Bizzaro Hodge co-levels (and very strange Ax-Katz/Cheval

Proof: Greater Angle is Subtended by Longer Side in a Triangle | Geometry

If one angle of a triangle is greater than another, then the side opposite the greater angle is longer than the side opposite the lesser angle. We prove this result in today's geometry video lesson. Note how this is a sort of extension of the converse of the isosceles triangle theorem, whi

​​Jeff Achter: ​​Local densities compute isogeny classes

Abstract: Consider an ordinary isogeny class of elliptic curves over a finite, prime field. Inspired by a random matrix heuristic (which is so strong it's false), Gekeler defines a local factor for each rational prime. Using the analytic class number formula, he shows that the associated i
