主讲内容：
The $Lp$-Minkowski problem deals with the existence of closed convex hypersurface with prescribed $p$-area measure. It was known that the problem admits a solution in sub-critical case $p>-n-1$ and does not have a solution in general in the critical case $p=-n-1$. But it remains unknown in the super-critical case $p<-n-1$. In this talk, we introduce new ideas to solve the problem for all super-critical exponents. A crucial ingredient in the proof is a topological method based on the calculation of the homology of a topological space of ellipsoids. The talk is based on recent joint work with Qiang Guang and Xu-Jia Wang.
