报告摘要:Diameter estimates of solutions to the Lp Aleksandrov problem for -1<p≤0 are established. As an application, we give a different proof of the existence of solutions to the even Lp Aleksandrov problem. We also find that p=-1 is a critical value for this problem by constructing some examples showing that the existence (resp. uniqueness) may fail for general even measures when p=-1 (resp. p<-1).
