摘要:   In this talk I will summarize three results on singularity analysis of PDEs. They are respectively the gradient blowup profile of nonlinear heat equations (joint with Hatem Zaag), the concentration of Davey-Stewartson II equation via surface theory (joint with Iskander A. Taimanov) and the time singularity of heat semigroup related to critical Sobolev embedding such as Brezis-Gallouet inequality (joint with Tohru Ozawa, Chenmin Sun and Taiki Takeuchi).
