应数学研究院许全华教授邀请,华东师范大学算子代数中心王智拓博士将于6月12日-6月15日来我校进行讲学活动,欢迎感兴趣的师生参加!

报告时间:6月13日15: 00

报告地点:数学系会议室(格物楼503)

报告题目:Constructive Renormalization of the Noncommutative Quantum Field Theory.

Abstrct: I will talk about the recent advancement in the construction of the 4 dimensional Grosse-Wulkenhaar model, which is a quantum field theory model defined on the 4 dimensional non-commutative Moyal space $R^4_\theta$. This model is exactly solvable and the 2 point and 4 point correlation functions are proved to satisfy the Osterwalder-Schrader axioms. I will also talk about the limit of their method and the construction of the 2 dimensional Grosse-Wulkenhaar model with the method of multi-scale loop vertex expansions.
