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...

Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

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...

Asymptotic Bounded Cohomology and Uniform Stability of high-rank lattices
Bharatram Rangarajan
11:00am|Simonyi 101 and Remote Access

In ongoing joint work with Glebsky, Lubotzky, and Monod, we construct an analog of bounded cohomology in an asymptotic setting in order to prove uniform stability of lattices in Lie groups (of rank at least two) with respect to unitary groups...
