On Expressiveness and Optimization in Deep Learning
2:00pm|Simonyi Hall 101

Three fundamental factors determine the quality of a statistical learning algorithm: expressiveness, optimization and generalization. The classic strategy for handling these factors is relatively well understood. In contrast, the radically different...

The structure of generic tame type Galois deformation rings
Bao Le Hung
4:30pm|Fine Hall 214, Princeton University

Deformation spaces of representations of Galois groups of p-adic fields with p-adic Hodge theoretic conditions play a central role in many arithmetic questions, such as the weight part of Serre's conjecture and modularity lifting theorems, yet they...

Kirillov theory and its applications
10:00am|Simonyi Hall 101

An orbit method (or Kirillov method) on compact $p$-adic groups establishes a one-to-one correspondence between irreducible representations and coadjoint orbits of dual blobs. After briefly recalling Howe’s Kirillov theory, we discuss its...

Mathematical Conversations

Hyperbolic geometry and quantum invariants in dimension 3
6:00pm|Dilworth Room

The end of the previous century saw radical changes to three-dimensional topology, which arose from two completely different approaches. One breakthrough came from Thurston's introduction of hyperbolic geometry into the field. The second one came...

Analysis Seminar

Polynomial Carleson operators along the paraboloid
Lillian Pierce
1:30pm|Simonyi Hall 101

The classical Carleson operator, which is intimately related to the Fourier transform, was an oscillatory singular integral operator with a linear phase. Motivated by a question of Eli Stein, recent consideration of Carleson operators has focused on...

Joint IAS/Princeton University Number Theory Seminar

Summation formulae and speculations on period integrals attached to triples of automorphic representations
4:45pm|Simonyi Hall 101

Braverman and Kazhdan have conjectured the existence of summation formulae that are essentially equivalent to the analytic continuation and functional equation of Langlands L-functions in great generality. Motivated by their conjectures and related...

Analytic aspects of Arthur's trace formula
Tobias Finis
1:45pm|Simonyi Hall 101

We will present an introduction to Arthur's trace formula from an analytic point of view. After recalling Arthur's regularization procedure, we will review the absolute convergence and continuity of the trace formula for a large natural class of...

Computer Science/Discrete Mathematics Seminar II

Heisenberg geometry and the Goemans—Linial SDP
10:30am|Simonyi Hall 101

Algorithmic graph partitioning tasks are naturally related to geometric issues. Over the past decades, several deeper connections of this type have emerged. In this talk, we will describe one example by showing that, up to lower order factors, the...
