Computer Science/Discrete Mathematics Seminar I

Some provable bounds for deep learning
11:15am|S-101

Deep learning, a modern version of neural nets, is increasingly seen as a promising way to implement AI tasks such as speech recognition and image recognition. Most current algorithms are heuristic and have no provable guarantees. This talk will...

Joint IAS/Princeton University Number Theory Seminar

The Landau-Siegel zero and spacing of zeros of \(L\)-functions
4:30pm|S-101

Let \(\chi\) be a primitive real character. We first establish a relationship between the existence of the Landau-Siegel zero of \(L(s,\chi)\) and the distribution of zeros of the Dirichlet \(L\)-function \(L(s,\psi)\), with \(\psi\) belonging to a...

Joint IAS/Princeton University Symplectic Geometry Seminar

GIT and \(\mu\)-GIT
Dietmar Salamon
1:00pm|S-101

In this lecture I will explain the moment-weight inequality, and its role in the proof of the Hilbert-Mumford numerical criterion for \(\mu\)-stability. The setting is Hamiltonian group actions on closed Kaehler manifolds. The major ingredients are...

Kinetic transport in quasicrystals
Jens Marklof
11:00am|West Bldg. Lect. Hall

Previous studies of kinetic transport in the Lorentz gas have been limited to cases where the scatterers are distributed at random (e.g. at the points of a spatial Poisson process) or at the vertices of a Euclidean lattice. In this talk I will...

Short Talks by Postdoctoral Members

Hamiltonian local models for symplectic derived stacks
Christopher Brav
2:30pm|S-101

After giving some motivation, we discuss the notion of symplectic form in derived algebraic geometry and explain how, in particular, it allows one to describe the local structure of moduli stacks of vector bundles on Calabi-Yau varieties in terms of...
