Non-equilibrium Dynamics and Random Matrices

The Sherrington-Kirkpatrick model and its diluted version I
Dmitry Panchenko
2:00pm|S-101

I will talk about two types of random processes -- the classical Sherrington-Kirkpatrick (SK) model of spin glasses and its diluted version. One of the main goals in these models is to find a formula for the maximum of the process, or the free...

How to Delegate Computations: The Power of No-Signaling
10:30am|S-101

The Martians built an amazingly fast computer and they run it to answer the great question of life, the universe and everything. They claim that the answer is 42. Will they be able to convince us that this is the right answer, assuming that we do...

Filtering the Grothendieck ring of varieties
2:00pm|S-101

The Grothendieck ring of varieties over \(k\) is defined to be the free abelian group generated by varieties over \(k\), modulo the relation \([X] = [Y] + [X \backslash Y]\) for all \(X\) and closed subvarieties \(Y\). Multiplication is induced by...

Two Structural Results for Low Degree Polynomials and Applications
11:15am|S-101

In this talk we will present two structural results concerning low degree polynomials over \(GF(2)\). The first states that for any degree d polynomial \(f\) in \(n\) variables over \(GF(2)\), there exists a subspace of \(GF(2)^n\) with dimension \(...

New combinatorial computations of embedded contact homology
Keon Choi
1:30pm|S-101

Embedded contact homology is an invariant of a contact three-manifold, which is recently shown to be isomorphic to Heegaard Floer homology and Seiberg-Witten Floer homology. However, ECH chain complex depends on the contact form on the manifold and...

Small gaps between primes
4:30pm|S-101

We will introduce a refinement of the `GPY sieve method' for studying small gaps between primes. This refinement will allow us to show that \(\liminf_n(p_{n+m}-p_n) \infty\) for any integer \(m\), and so there are infinitely many bounded length...

Non-displaceable Lagrangians via minimal model transitions
Chris Woodward
4:30pm|Fine 314, Princeton University

I will discuss some results, some older and some newer, on the general idea that in many birationally-Fano cases, generators of the Fukaya category seem to arise from transitions in the minimal model program. A specific result from a couple of years...
