报告摘要: In this paper, we prove the hot spots conjecture for n-axes symmetric domain in R^n by continuity method. More precisely, we show that the odd Neumann eigenfunctions with lowest nonzero eigenvalues are the Morse functions on the boundary that have exactly two non-degenerate critical points and the eigenfunctions are monotone in the direction from minimum point to maximum point. As a consequence, we show that hot spots conjecture holds for such kind of domains provided that the second Neumann eigenvalue is simple. And we also settle the Jerison and Naridashvili's conjecture for the domains with n-axes symmetry or hyperbolic drum.
