Special Year Seminar I

Combinatorics in Quantum K-theory Schubert Calculus
Cristian Lenart
2:00pm|Simonyi 101

I will discuss various applications of a combinatorial model for the (torus equivariant) quantum K-theory of flag manifolds G/B, called the quantum alcove model. This is a uniform model for all Lie types, based on Weyl group combinatorics. It first...

Connections to Schubert Calculus Learning Seminar

Enumerating Smooth-Like Permutations Via the Geometry of Schubert Varieties
Edward Richmond
3:30pm|Simonyi 101

In 1984, Ryan showed that any smooth Schubert variety in type A is an iterated fiber-bundle of Grassmannian varieties. Later, Haiman calculated the generating function for the number of smooth permutations (equivalently smooth Schubert varieties) of...

FRB science results from CHIME
Kendrick Smith
3:30pm|U.Penn, David Rittenhouse Laboratory, 4E19

Fast radio bursts (FRBs) are a recently discovered, poorly understood class of transient event, and understanding their origin has become a central problem in astrophysics. I will present FRB science results from CHIME, a new interferometric...

Special Year Seminar II

A Reduction of the F-Conjecture
Angela Gibney
10:00am|Simonyi 101

The long-standing F-Conjecture asserts that there is a very simple description for the closed cone of effective curves on the moduli space M_{g,n}\bar of stable n-pointed curves of genus g as being determined by a finite collection of so-called F...

From Few-Body to Stellar Clusters: How Gas Reshapes Dynamical Evolution
11:00am|Bloomberg Lecture Hall

Gas-rich environments are ubiquitous in various scales, from protoplanetary disks to star clusters and galaxies. Dynamics in gas-rich environments are substantially different and give rise to unique astrophysical phenomena, along with enhancing the...
