Title: Gravitational edge mode for 2D gravity

Abstract: In this seminar, I will discuss the gravitational edge mode of the two-dimensional gravity. First, I will review the gravitational edge mode from the bosonic JT gravity. I will discuss the issues related to dilaton and PSL(2,R) gauging in the derivation of the Schwarzian action. I will revisit the derivation of Schwarzian action for the edge mode by using the inversion formula of Schwarzian derivative. I will explain how to obtain N=1 super-Schwarzian action. I will also discuss the relation between osp(2,1) gauging and isometry.
