Sharp Spectral Gap Estimates on Manifolds under Integral Ricci Curvature Bounds
Abstract
We prove sharp spectral gap estimates on compact manifolds with integral curvature bounds. We generalize the results of Kröger (Kröger '92) as well as of Bakry and Qian (Bakry-Qian '00) to the case of integral curvature and confirm the conjecture in (Ramos et al. '20).
