Abstract

Let M be a connected complete noncompact n-dimensional Riemannian manifold with a base point p ∈ M whose radial sectional curvature at p is bounded from below by that of a noncompact surface of revolution which admits a finite total curvature where n ≥ 2. Note here that our radial curvatures can change signs wildly. We then show that limt→∞ vol Bt(p)/tn exists where vol Bt(p) denotes the volume of the open metric ball Bt(p) with center p and radius t. Moreover we show that in addition if the limit above is positive, then M has finite topological type and there is therefore a finitely upper bound on the number of ends of M.
