摘 要:
It is well known that the spectrum of the Laplacian on a compact manifold is discrete. We proved that the drift Laplacian on a proper self shrinker also has a discrete spectrum. In this talk, I would like to present some recent results on the estimates of eigenvalues of both Laplacians on compact and noncompact $f$-minimal hypersurfaces.
