Joint IAS/Princeton University Symplectic Geometry Seminar

Log geometric techniques for open invariants in mirror symmetry
Hülya Argüz
4:30pm|Fine 322, Princeton University

We would like to discuss an algebraic-geometric approach to some open invariants arising naturally on the A-model side of mirror symmetry.

Joint IAS/Princeton University Symplectic Geometry Seminar

Positive loops of loose Legendrians and applications
Guogang Liu
3:00pm|Fine 224, Princeton University

In this talk, I will give a simple and geometrical proof of the following theorem from my thesis: Every loose Legendrian is in a positive loop amongst Legendrian embeddings. The idea is that we add wrinkles to a loose Legendrian and rotate the...

Computer Science/Discrete Mathematics Seminar II

Sum of squares lower bounds for refuting any CSP
10:30am|S-101

Let $P:\{0,1\}^k \to \{0,1\}$ be a $k$-ary predicate. A random instance of a constraint satisfaction problem (CSP(P)) where each of the $\Delta n$ constraints is $P$ applied to $k$ literals on $n$ variables chosen at random is unsatisfiable with...

Members’ Seminar

Points and lines
1:15pm|S-101

The Fukaya category of a symplectic manifold is a robust intersection theory of its Lagrangian submanifolds. Over the past decade, ideas emerging from Wehrheim--Woodward's theory of quilts have suggested a method for producing maps between the...

Computer Science/Discrete Mathematics Seminar I

On gradient complexity of measures on the discrete cube
Ronen Eldan
11:15am|S-101

The motivating question for this talk is: What does a sparse Erdős–Rényi random graph, conditioned to have twice the number of triangles than the expected number, typically look like? Motivated by this question, In 2014, Chatterjee and Dembo...

Joint IAS/Princeton University Number Theory Seminar

Arithmetic and geometry of Picard modular surfaces
4:30pm|S-101

Of interest are (i) the conjecture of Bombieri (and Lang) that for any smooth projective surface $X$ of general type over a number field $k$, the set $X(k)$, of $k$-rational points is not Zariski dense, and (ii) the conjecture of Lang that $X(k)$...

Mathematical Conversations

Negative correlation and Hodge-Riemann relations
6:00pm|Dilworth Room

All finite graphs satisfy the two properties mentioned in the title. I will explain what I mean by this, and speculate on generalizations and interconnections.
