Joint IAS/Princeton University Symplectic Geometry Seminar

Representations are sheaves' for Legendrian 2-weaves
Kevin Sackel
4:00pm|Fine 314 and Remote Access

 

Given a trivalent plane graph embedded in the Euclidean plane (up to isotopy), Treumann and Zaslow constructed and studied a certain associated Legendrian surface embedded in standard contact $R^{5}$, nowadays referred to as a Legendrian 2-weave...

Members' Colloquium

On the unpredictability of fluid motions
Dallas Albritton
2:00pm|Simonyi Hall 101 and Remote Access

The fundamental equations of fluid dynamics exhibit non-uniqueness. Is this a mathematical fluke, or do the equations fail to uniquely predict the motion of fluids? In this colloquium, we present recent mathematical and physical progress toward...

Computer Science/Discrete Mathematics Seminar I

Online Bipartite Matching and Adwords
Vijay V. Vazirani
11:15am|Simonyi 101 and Remote Access

Over the last three decades, the online bipartite matching (OBM) problem has emerged as a central problem in the area of Online Algorithms. Perhaps even more important is its role in the area of Matching-Based Market Design.  The resurgence of this...

Dimers, networks, and integrable systems
Anton Izosimov
9:15am|Remote Access

I will review two combinatorial constructions of integrable systems: Goncharov-Kenyon construction based on counting perfect matchings in bipartite graphs, and Gekhtman-Shapiro-Tabachnikov-Vainshtein construction based on counting paths in networks...

Arithmetic statistics and graded Lie algebras
Jef Laga
3:00pm|Remote Access Only - see link below

I will explain how various results in arithmetic statistics by Bhargava, Gross, Shankar and others on 2-Selmer groups of Jacobians of (hyper)elliptic curves can be organised and reproved using the theory of graded Lie algebras, following earlier...
