Princeton University Galread [Galactic/Extragalactic Reading Group]

A Measurement of the Galactic Plane Mass Density from Binary Pulsar Accelerations
11:00am|Virtual Meeting

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...

Princeton University Extrasolar Planet Discussion Group

Planet Formation and the Composition of Rocky Planets
Amy Bonsor
12:00pm|Virtual Meeting

The composition of a rocky planet tells us about the structure of the planet, its geology, what it might be like on the surface and ultimately whether or not it hosts life. Identifying the key processes during planet formation that control...

Marston Morse Lectures

Statistical physics of random CSPs
Nike Sun
3:00pm|Remote Access via Zoom videoconferencing (link below)

I will describe recent progress in determination of asymptotic behavior in random constraint satisfaction problems, including the independent set problem on random graphs, random regular NAE-SAT, and random SAT. The results include sharp phase...

Analysis Seminar

From hyperbolic billiards to statistical physics
4:30pm|Remote Access

Consider a point particle flying freely on the torus and elastically bouncing back from the boundary of fixed smooth convex obstacles. This is the celebrated Sinai billiard, a rare example of a deterministic dynamical system where rigorous results...

Computer Science/Discrete Mathematics Seminar II

On Chen’s recent breakthrough on the Kannan-Lovasz-Simonovits conjecture and Bourgain's slicing problem
10:30am|Simonyi Hall 101 and Remote Access - see Zoom link below

In the mid 80's, Bourgain asked the following question: Is there a universal constant $c>0$ such that every compact convex set $K$ in $R^n$, of unit volume, must contain a slice (namely, a set of the form $K \cap H$ for some affine hyperplane $H$)...

SL2 Seminar

Perverse sheaves on Grassmannians via microlocal geometry
6:00pm|Remote Access

I will present a finite-dimensional quiver algebra whose representations are equivalent to the category of Schubert-constructible perverse sheaves on the Grassmannian $Gr(k,n)$. The functor inducing the equivalence is constructed by analyzing the...
