Lie groupoid structures on regular Donaldson moduli spaces and applications.

题目:Lie groupoid structures on regular Donaldson moduli spaces and applications.    

报告人:乔帅格(北京大学)    

摘要:In the study of instanton moduli spaces, e.g. Kotschick-Morgan conjecture, Witten conjecture, K-theoretical Donaldson invariant,…, Lie groupoid structure on the moduli space and its compactification is required. 

In this talk, I will show that the bubble tree compactification of regular Donaldson moduli space admit s a Lie groupoid structure. Furthermore, we will discuss its application to Kotschick-Morgan conjecture. 

This is a joint work with Bohui Chen and Bai-ling Wang.
