講座簡(jiǎn)介：
In this talk, I will show the concentration compactness phenomenon for nonnegative solutions of the Sobolev critical fast diffusion equations in bounded domains with the vanishing Dirichlet boundary condition. Inspired by the Brezis-Nirenberg problem, I will present the extinction behavior of the solutions if the equations have a favorable zero order term in dimension four and higher. Moreover, the sharp extinction rate is obtained. This is joint with Tianling Jin.
