Computer Science/Discrete Mathematics Seminar I

Communication complexity of approximate Nash equilibria
Aviad Rubinstein
11:15am|West Building Lecture Hall

For a constant $\epsilon$, we prove a $\mathrm{poly}(N)$ lower bound on the communication complexity of $\epsilon$-Nash equilibrium in two-player $N \times N$ games. For $n$-player binary-action games we prove an $\exp(n)$ lower bound for the...

Homological Mirror Symmetry (Mini-Course)

Logarithmic Gromov-Witten invariants
10:45am|S-101

Following Katz-Nishinou, we will compute the number of lines on a quintic threefold in $\mathbb P^4$ by degenerating the quintic to the union of coordinate hyperplanes. This motivates degeneration formulae in Gromov-Witten theory that I will give...

Joint IAS/Princeton University Number Theory Seminar

The arithmetic of noncongruence subgroups of $\mathrm{SL}(2,\mathbb Z)$
William Chen
4:30pm|Fine 214, Princeton University

After beginning by giving a brief overview of how one can think of noncongruence modular curves as moduli spaces of elliptic curves with G-structures, we will discuss how these moduli interpretations fits into the greater body of knowledge...

Mathematical Conversations

Phase transitions and symmetry breaking
6:00pm|Dilworth Room

In broad terms, a phase transition is a variation in the qualitative behavior of a system under changes of some parameter. For instance, as the temperature is changed, water goes through a gaseous, a liquid, and several solid phases, each of which...
