Computer Science/Discrete Mathematics Seminar II

Arithmetic Progressions in Primes
Madhur Tulsiani
10:30am|S-101

I will discuss the Green-Tao proof for existence of arbitrarily long arithmetic progressions in the primes. The focus will primarily be on the parts of the proof which are related to notions in complexity theory. In particular, I will try to...

Number Theory Related to Quantum Chaos
2:00pm|S-101

Quantum chaos is concerned with properties of eigenvalues and eigenfunctions of "quantized Hamiltonians". For instance, can classical chaos be detected by looking at the spacings between eigenvalues? Another problem is if classical ergodicity forces...

Computer Science/Discrete Mathematics Seminar I

Privacy of Dynamic Data: Continual Observation and Pan Privacy
Moni Naor
11:15am|S-101

Research in the area of privacy of data analysis has been flourishing recently, with a rigorous notion such as differential privacy regarding the desired level of privacy and sanitizing algorithms matching the definition for many problems. Most of...

Special Geometry of Materials Seminar

What does the Modular Group Have to do With Materials?
4:00pm|S-101

Simple cell decompositions of surfaces are in one to one correspondence with certain conjugacy classes of subgroups of the modular group. Polycrystalline structures in 2 dimensional materials give rise to statistical simple cell decompositions of...

Special Seminar

Spectral Edge Statistics of Random Band and Sparse Matrices
Alexander Sodin
2:00pm|S-101

We discuss the distribution of the extreme eigenvalues for several classes of large (N X N) Hermitian random matrices. For a class of sparse matrices, the distribution is approximately Tracy--Widom. For band matrices with band width W(N) , the...

Joint IAS/Princeton University Number Theory Seminar

Slope Filtrations in Families
4:30pm|Fine Hall -- 214

In the 21st-century approach to p-adic Hodge theory, one studies local Galois representations (and related objects) by converting them into modules over certain power series rings carrying certain extra structures (Frobenius actions and derivations)...
