Symplectic Geometry Seminar

Compactness Problems in Counting Special Lagrangians and Fueter Sections
Saman Habibi Esfahani
1:00pm|Simonyi 101 and Remote Access

This talk is based on joint work with Yang Li. I will discuss the problem of counting special Lagrangians in Calabi-Yau 3-folds and Fueter sections to define new numerical and Floer-theoretic invariants. The key challenges are the non-compactness...

IAS Amplitudes Group Meeting

Rays, Residues and the Moduli Space of Polygons
Nick Early
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: We describe a (surprisingly) novel, uniform formula for all inverse propagators appearing in $tr(\phi^3)$ amplitudes which are dual to a basis of rays of the tropical Grassmannian $TropG(2,n)$.  Our formula manifests the standard kinematic...

Joint IAS/PU Groups and Dynamics Seminar

Short Curves of End-Periodic Mapping Tori
Brandis Whitfield
4:30pm|Simonyi 101

Fibered 3-manifolds are those constructed via surface homeomorphisms. Given such a manifold with pseudo-Anosov monodromy, much is already known about how topological data of the mapping class determine geometric information about the hyperbolic 3...
