Computer Science/Discrete Mathematics Seminar I

Lower Bounds for Set-Multilinear Branching Programs
Shubhangi Saraf
11:00am|Simonyi 101 and Remote Access

In this talk, I will discuss lower bounds for a certain set-multilinear restriction of algebraic branching programs. The significance of the lower bound and the model is underscored by the recent work of Bhargav, Dwivedi, and Saxena (2023), which...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
11:00am|Zoom and Peyton Hall, Grand Central

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Members' Colloquium

Triangulated Surfaces in Moduli Space
2:00pm|Simonyi 101 and Remote Access

Triangulated surfaces are Riemann surfaces formed by gluing together equilateral triangles. They are also the Riemann surfaces defined over the algebraic numbers. Brooks, Makover, Mirzakhani and many others proved results about the geometric...

Joint IAS/Princeton Arithmetic Geometry Seminar

Microlocal Sheaves and Affine Springer Fibers
Pablo Boixeda Alvarez
3:30pm|Fine 322, Princeton University

The resolutions of Slodowy slices $\tilde{S}_{e}$ are symplectic varieties that contain the Springer fiber $(G/B)_{e}$ as a Lagrangian subvariety. In joint work with R. Bezrukavnikov, M. McBreen and Z. Yun, we construct analogues of these spaces for...

Computer Science/Discrete Mathematics Seminar II

Incidence Bounds via Extremal Graph Theory
Istvan Tomon
10:30am|Simonyi Hall 101 and Remote Access

A cornerstone result in geometry is the Szemerédi–Trotter theorem, which gives a sharp bound on the maximum number of incidences between $m$ points and $n$ lines in the real plane. A natural generalization of this is to consider point-hyperplane...

Institute for Advanced Study Astrophysics Seminar

Testing Galaxy Formation Models with Large-scale Surveys of the Milky Way Stellar Halo
Emily Cunningham
11:00am|Bloomberg Lecture Hall

While the vast majority of the light from our galaxy comes from the Galactic disk, the vast majority of the mass of the Milky Way (MW) is in its dark matter halo. Because we cannot directly observe the MW's dark matter halo, we must use luminous...
