Special Year Seminar II

On the Extremals of the Khovanskii-Teissier Inequality
Ramon Van Handel
10:00am|Simonyi 101

The Khovanskii-Teissier inequality provides the fundamental log-concavity property of intersection numbers of divisors of algebraic varieties, extending the Alexandrov-Fenchel inequality of convex geometry. In this talk I will explain, and attempt...

What is a p-adic zeta function?
Ellen Eischen
1:00pm|Simonyi 101 and Remote Access

In the 1850s, Kummer discovered some striking congruences mod powers of a prime number p between values of the Riemann zeta function at negative odd integers.  This was part of his attempt to understand structural aspects of certain algebraic...

On the Arithmetic of Genus 4 Curves
Jiahui Gao
3:30pm|Simonyi 101 and Remote Access

We propose and study a new arithmetic invariant of non-hyperelliptic genus-4 curves: a canonical “quadratic” point on the Jacobian, defined by the two natural degree-2 maps to projective lines. Building on Xue’s result, that this point is...

IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Morse Theory of Loop Spaces and Hecke Algebras
Roman Krutowski
9:15am|Remote Access

One can associate an HDHF (symmetric) wrapped Fukaya category to a Liouville domain by counting higher genus curves, which are required to be branched covers. For the cotangent bundle of an orientable surface with genus at least one Honda, Tian, and...

IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Markov Staircases
Joé Brendel
9:15am|Remote Access

In this talk, we will discuss new infinite symplectic staircases. Much recent progress has been made in the study of infinite symplectic staircases arising from embedding problems of standard ellipsoids into various symplectic four-manifolds. We...
