## Geometry Seminar

**Date:** August 26, 2019

**Time:** 3:00PM - 3:50PM

**Location:** BLOC 628

**Speaker:** Guangbo Xu, Texas A&M University

**Title:** *Introduction to Floer homology*

**Abstract:** In this talk, after reviewing the classical finite dimensional Morse theory, I will give a short introduction to various versions of Floer homology theories, for example, Lagrangian intersection Floer homology in symplectic geometry and instanton Floer homology in gauge theory. I will also explain the conceptual picture of the celebrated Atiyah-Floer conjecture. Non-experts, especially graduate students are welcome.
