题目：Formal exponential maps and L-infinity structure
报告人：Prof. Ping Xu（Pennsylvania State University, USA）
摘要:
Exponential maps arise naturally in the contexts of Lie theory and smooth manifolds. The infinite jets of these classical exponential maps are related to the Poincar/'e--Birkhoff--Witt isomorphism and the complete symbols of differential operators. We will investigate the question how to extend these maps to graded manifolds by introducing formal exponential maps in a purely algebraic way.
As an application, we will show there is an L-infinity structure in connection with the Atiyah class of a dg manifold.
