Vanishing S-curvature of Randers spaces

Differential Geometry 2022-04-19 v2

Abstract

We give a necessary and sufficient condition on a Randers space for the existence of a measure for which Shen's S-curvature vanishes everywhere. Moreover, such a measure coincides with the Busemann-Hausdorff measure up to a constant multiplication.
