Title: On manifold with positive spectrum

Abstract: In this talk, I will first present my joint work with Bobo Hua on manifold with positive spectrum with respect to a Schrodinger operator. On a relevant topic, I will then present the discontinuity phenomena of eigenfunctions on singular space and its applications in constructing manifold with essential spectrum gaps.
