Joint IAS/Princeton University Symplectic Geometry Seminar

On normal crossings symplectic divisors
1:30pm|Fine 322, Princeton University

I will describe purely symplectic notions of normal crossings divisor and configuration. They are compatible with the existence of the desired auxiliary almost Kahler structures, provided ``existence" is suitably interpreted. These notions lead to a...

Joint IAS/Princeton University Number Theory Seminar

Selmer groups, automorphic periods, and Bloch-Kato Conjecture
Yifeng Liu
4:30pm|Fine 214, Princeton University

The Bloch-Kato Conjecture, which generalizes the B-SD Conjecture to higher dimensional varieties, predicts a relation between certain Selmer group and L-function. The famous works of Gross-Zagier and Kolyvagin give results for elliptic curves when...

Joint IAS/Princeton University Number Theory Seminar

The polynomial method
Jordan Ellenberg
1:30pm|Fine 214, Princeton University

In 2008, Zeev Dvir gave a surprisingly short proof of the Kakeya conjecture over finite fields: a finite subset of $F_q^n$ containing a line in every direction has cardinality at least $c_n q^n$. The "polynomial method" introduced by Dvir has led to...

Workshop on Topology: Identifying Order in Complex Systems

The law of Aboav--Weaire and extensions
5:00pm|S-101

In two-dimensional grain structure, one observes that grains with a small number of sides tend to be surrounded by grains with a large number of sides, and vice-versa. The Law of Aboav--Weaire gives this observation a mathematical formulation, that...

Workshop on Topology: Identifying Order in Complex Systems

Topological similarity of random cell complexes, and applications
Benjamin Schweinhart
3:30pm|S-101

Although random cell complexes occur throughout the physical sciences, there does not appear to be a standard way to quantify their statistical similarities and differences. I'll introduce the notions of a 'swatch' and a 'cloth', which provide a...
