Title: 4-dimensional Space forms as determined by the volumes of small geodesic balls
(Submitted on 24 Apr 2024)
Abstract: Gray-Vanhecke conjectured that the volumes of small geodesic balls could determine if the manifold is a space form, and provided a proof for the compact 4-dimensional manifold, and some cases. In this paper, similar results for the 4-dimensional case are obtained, based upon tensor calculus and classical theorems rather than the topological characterizations in [6].
