Sharp integral bound of scalar curvature on $3$-manifolds

Differential Geometry 2025-05-16 v1

Abstract

It is shown that the integral of the scalar curvature on a geodesic ball of radius RR in a three-dimensional complete manifold with nonnegative Ricci curvature is bounded above by 8πR8\pi R asymptotically for large RR provided that the scalar curvature is bounded between two positive constants.
