Abstract:
Let $M$ be an $n$-dimensional, complete, simply connected Riemannian manifold. In this paper we show that if the sectional curvature is bounded above by $- k \leq 0$ and the Ricci curvature is bounded above by $- \alpha \leq 0$, then the spectrum of the Laplacian on $M$ is bounded below by $[\alpha + (n - 1)(n - 2)k]/4$. This improves a previous result due to H. P. McKean.References
