Special Year Seminar II

Introduction to Equivariant K-theory
10:00am|Simonyi 101

K-theory arose in the 1950s from Grothendieck’s formulation of the Riemann-Roch theorem – that is, from attempts to calculate spaces of sections of vector bundles on a variety X via intersection theory on X.  An equivariant version was introduced...

Institute for Advanced Study Astrophysics Seminar

Three Preludes on a Theme of Magnetars: Early Spindown, Nucleosynthesis, and Giant Flares
Todd Thompson
11:00am|Bloomberg Lecture Hall

Neutron stars born with magnetic fields greater than 1014 G (“magnetars”) are common in the Galaxy. Approximately 10 - 50% of the young neutron star population possesses such field strengths. These objects exhibit very slow rotation, spectacular...

What is...?

What is an Open Book Decompositions?
1:00pm|Simonyi Classroom (S-114)

Open book decompositions provide a topological decomposition of a given manifold. We focus on dimension three. While the definition seems to be purely topological, it encodes information about fibered knots, surface dynamics, contact structures of...

Princeton University High Energy Theory Seminar

Black Hole Mimickers: BPS Case Study
Yoav Zigdon
2:30pm|Jadwin Hall, 4th Floor, PCTS Room 407

Abstract: Type II string theory has BPS brane bound states that carry two charges. I will show that their microcanonical ensemble average corresponds to a spherical black hole mimicker, which possesses a long throat, shares the same asymptotic data...

Joint PU/IAS Number Theory

Multiple Dirichlet Series, Moments of L-functions, and Symmetry
Ian Whitehead
3:30pm|*Princeton University, Fine 214*

I will discuss joint work in progress with Will Sawin on function field multiple Dirichlet series constructed based on a set of axioms from algebraic geometry. These series have applications to moments of Dirichlet L-functions for characters of...
