Cyril Letrouit (MIT) – Nodal sets of eigenfunctions of sub-Laplacians
Phillips Hall 328Mode: In-Person Title: Nodal sets of eigenfunctions of sub-Laplacians Abstract: Nodal sets of eigenfunctions of elliptic operators on compact manifolds have been studied extensively over the past decades. In a recent work, we initiated the study of nodal sets of … Continued

Dr. Rebecca Goldin, George Mason University – On positivity for flag manifolds and Hessenberg spaces
Phillips Hall 332Mode: In-Person Title: On positivity for flag manifolds and Hessenberg spaces Abstract: “Positivity” is a phenomenon involving the intersection of subvarieties in the presence of enough structure to ensure that intersection points are positively oriented, among other generalizations. It has … Continued
Dr. Anders Buch, Rutgers – Pieri formulas for the quantum K-theory of cominuscule Grassmannians
Phillips Hall 385Mode:In-Person Title: Pieri formulas for the quantum K-theory of cominuscule Grassmannians Abstract: The quantum K-theory ring QK(X) of a flag variety X encodes the K-theoretic Gromov-Witten invariants of X, defined as arithmetic genera of Gromov-Witten varieties parametrizing curves meeting fixed … Continued
Demetre Kazaras (Duke) – The geometry of scalar curvature and mass in general relativity
Phillips Hall 328Mode: In-Person Title: The geometry of scalar curvature and mass in general relativity Abstract: In general relativity, the space we inhabit is modeled by a Riemannian manifold. The fundamental restriction this theory places upon spatial geometry is a lower bound … Continued

Zoe Wyatt (King’s College) – Global stability of Kaluza-Klein spacetimes
Phillips Hall 328Mode: In-Person Title: Global stability of Kaluza-Klein spacetimes Abstract: Spacetimes formed from the Cartesian product of Minkowski space and a flat torus play an important role as toy models for theories of supergravity and string theory. In this talk I … Continued
