题目： Kontsevich-Duflo Theorem
报告人：Prof. Ping Xu（Pennsylvania State University, USA）
摘要: In late 1990's, Kontsevich revolutionized the field of deformation quantization with his formality theorem, which implies, among many things, the existence of deformation quantizations for all Poisson manifolds. Amazingly, it turned out that the classical Duflo theorem is also a consequence of Kontsevich's formality construction. Kontsevich also discovered a similar phenomenon in complex geometry.
In this talk, I will discuss Kontsevich-Duflo theorem.

题目：Algebraic exponential maps
报告人：Prof. Mathieu Stienon （Pennsylvania State University, USA）
摘要: Exponential maps arise naturally in the contexts of Lie theory and connections on smooth manifolds. We will explain how exponential maps can be understood algebraically, how these maps can be extended to graded manifolds and how this problem leads naturally to Dolgushev-Fedosov resolutions.
