Abstract：

In this talk, we will introduce our ongoing project on Sobolev inequalities in the context of quantum markov semigroup. We mainly focus on the study of the relations between Sobolev inequalities and other typical functional inequalities, including logarithmic Sobolev inequalities, Nash inequalities and Ultra-contractivity. The talk is based on joint work with Li Gao and Marius Junge.
