Computer Science/Discrete Mathematics Seminar I

Learning arithmetic circuits in the average case via lower bounds
Ankit Garg
11:00am | Simonyi Hall 101
The problem of learning arithmetic circuits is the following: given a polynomial as a black box that is promised to have a small arithmetic circuit computing it, can we find...

Princeton University/Institute for Advanced Study Galread [Galactic/Extragalactic Reading Group]

Elemental Abundances in M31: A Comparative Analysis of Iron and Alpha Element Abundances in the Outer Disk, Giant Stellar Stream, and Inner Halo of M31
Discussion Leader Ivanna Escala
11:00am | Princeton University, Peyton Hall, Grand Central
Each week, we hold a relatively informal seminar/discussion series in Peyton Hall with an emphasis on extra-galactic and large-scale structure astrophysics. During Galread a...

Princeton University Exoplanet Discussion Group

General Discussion
12:15pm | Princeton University, Peyton Hall, Room 140
This is an informal hour long meeting during which we discuss recent results in the field of exoplanets, with occasional forays into stellar astrophysics and planetary...

Princeton University/Institute for Advanced Study Early Universe/Cosmology Lunch Discussion

Extreme Emission Line Galaxies (EELs) as a Platinum Redshift Sample for Galaxy Clustering Measurements with LSST
Adam Broussard
12:30pm | Institute for Advanced Study, West Building, West Seminar Room
The Large Synoptic Survey Telescope (LSST) is projected to observe approximately 25 billion galaxies, which will be incredibly useful for measurements of galaxy clustering and...

Members' Seminar

tba Length and volume in symplectic geometry
Daniel Cristofaro-Gardiner
2:00pm | Simonyi Hall 101
Symplectic capacities are measurements of symplectic size.  They are often defined as the lengths of certain periodic trajectories of dynamical systems, and so they connect...

High Energy Theory Seminar

ZZ Instantons and the Non-Perturbative Dual of c=1 String Theory
Bruno Balthazar
2:30pm | Jadwin Hall, Room A07
We study the effect of ZZ instantons in c = 1 string theory, and demonstrate that they give rise to non-perturbative corrections to closed string scattering amplitudes that do...
Oct 21

Symplectic Dynamics/Geometry Seminar

Koszul duality and Knot Floer homology
Thomas Hockenhull
3:30pm | *Princeton University, Fine Hall 224*
‘Koszul duality’ is a phenomenon which algebraists are fond of, and has previously been studied in the context of '(bordered) Heegaard Floer homology' by Lipshitz, Ozsváth and...

Analysis Seminar

Strong ill-posedness of the logarithmically regularized 2D Euler equations in the borderline Sobolev space
Hyunju Kwon
5:00pm | Simonyi Hall 101
The well-posedness of the incompressible Euler equations in borderline spaces has attracted much attention in recent years. To understand the behavior of solutions in these...

Computer Science/Discrete Mathematics Seminar I

Towards a theory of non-commutative optimization: geodesic 1st and 2nd order methods for moment maps and polytopes
Rafael Oliveira
10:30am | Simonyi Hall 101
Scaling problems, such as operator scaling and tensor scaling, have recently found several applications in diverse areas of math and CS. They have been used to give efficient...
