Spectral positivity and Riemannian coveringsmath.DG

Let $(M,g)$ be a complete non-compact Riemannian manifold. We consider operators of the form $Δ_g + V$ , where $Δ_g$ is the non-negative Laplacian associated with the metric $g$ , and $V$ a locally integrable function. Let $ρ: (\hat{M},\hat{g}) \to (M,g)$ be a Riemannian covering, with Laplacian $Δ_{\hat{g}}$ and potenti…
