Special Year Seminar I

KP Solitons, Tropical Curves, and Voronoi Cells
2:00pm|Simonyi 101

The Kadomtsev-Petviashvili (KP) Equation has deep connections to algebraic curves, with solutions constructed from Riemann theta functions in the style of Krichever. As a curve undergoes tropical degeneration, its theta function simplifies to a...

Connections to Schubert Calculus Learning Seminar

Schubert Polymatroids
3:30pm|Simonyi 101

We discuss some equivariant compactifications of linear subspaces, controlled by the combinatorics of polymatroids. Open problems of interest to the Schubert calculus community will be emphasized. Joint with Colin Crowley & Botong Wang.

Mathematical Conversations

Aperiodic Square Tilings and Lattices in Products of Trees
6:00pm|Simons Hall Dilworth Room

We will consider finite collections of squares tiles, and ask when we can tile the whole plane in an interesting way. This question is related to the algebraic structure of ‘lattices in products of trees’, which are discrete groups acting...

Special Year Seminar II

Measures on Combinatorial Objects
Andrew Snowden
10:00am|Simonyi 101

Suppose given a class of finite combinatorial structures, such as graphs or total orders. Nate Harman and I recently introduced a notion of measure in this context: this is a rule assigning a number to each structure such that some axioms are...

Joint PU/IAS Number Theory

There Are Infinitely Many Elliptic Curves Over the Rationals of Rank 2
David Zywina
3:30pm|Simonyi 101 and Remote Access

For an elliptic curve E defined over Q, the Mordell-Weil group E(Q) is a finitely generated abelian group. We prove that there are infinitely many elliptic curves E over Q for which E(Q) has rank 2. Our elliptic curves will be given by explicit...

Alexia Corradini (University ofCambridge) :The Lagrangian Ceresa Cycle

In algebraic geometry, the Ceresa cycle provided one of the first examples of a nullhomologous cycle which is not algebraically trivial. I will explain how one can obtain a...

Symplectic Geometry Seminar

Legendrian Non-Squeezing via Microsheaves
Eric Kilgore
1:00pm|Simonyi 101 and Remote Access

In this talk I will explain some quantitative embedding results for Legendrian submanifolds of pre-quantization spaces. To start, I will recall some contact non-squeezing results for domains, and present an elementary proof of Legendrian non...
