Computer Science/Discrete Mathematics Seminar I

High-Confidence Predictions under Adversarial Uncertainty
11:15am|S-101

We study the setting in which the bits of an unknown infinite binary sequence x are revealed sequentially to an observer. We show that very limited assumptions about x allow one to make successful predictions about unseen bits of x . Our main focus...

Joint IAS/Princeton University Number Theory Seminar

Sup-norms, Whittaker Periods and Hypergeometric Sums
4:30pm|Fine Hall -- 214

We begin with a survey of recent results on the problem of bounding the sup-norm of automorphic forms. If f is a cuspidal automorphic forms on a reductive group G it is classical to study its value distribution and in the particular the maximum of...

Mathematical Conversations

Euler, Riemann and Chebyshev
6:00pm|Dilworth Room

The Riemann zeta function is the most important function of number theory, and a great part of modern research in number theory is dedicated to its study and the study of its relatives the L-functions. It was Riemann who revolutionized number theory...

How Large is the Shadow of a Symplectic Ball?
Alberto Abbondandolo

Geometric and Numerical Approaches to KAM Theory
2:00pm|S-101

We review some recent developments in KAM theory. By exploiting some identities of a geometric nature, one can obtain iterative steps which lead to numerical algorithms and which can follow the tori till breakdown. We present theoretical results in...

Randomness Extraction: A Survey
10:30am|S-101

A randomness extractor is an efficient algorithm which extracts high-quality randomness from a low-quality random source. Randomness extractors have important applications in a wide variety of areas, including pseudorandomness, cryptography...

Toward Enumerative Symplectic Topology
2:00pm|S-101

Enumerative geometry is a classical subject often concerned with enumeration of complex curves of various types in projective manifolds under suitable regularity conditions. However, these conditions rarely hold. On the other hand, Gromov-Witten...

Graphlets: A Spectral Perspective for Graph Limits
Fan Chung
11:15am|S-101

To examine the limiting behavior of graph sequences, many discrete methods meet their continuous counterparts, leading to numerous theoretical and applicable advancements. For dense graph sequences, the graph limits have recently been well developed...

Workshop on Topology: Identifying Order in Complex Systems

The Taming olf the Screw: or How I Learned to Stop Worryhing and Love Elliptic Functions
Elisabetta Matsumoto
3:30pm|Rutgers University, Hill Center, Room 705

Topological defects pervade a wide range of physical systems, from superconductors to smectic liquid crystals. The behavior and interactions of such singularities impart many materials with a wealth of rich behavior. Just as flux vortices in the...
