Almost Nonnegative Ricci curvature and new vanishing theorems for genera

Differential Geometry 2022-09-27 v1

Abstract

We derive several vanishing theorems for genera under almost nonnegative Ricci curvature and infinite fundamental group, which includes Todd genus, A^\widehat{A}-genus, elliptic genera and Witten genus. A vanishing theorem of Euler characteristic number for almost nonnegatively curved Alexandrov spaces is also proved.
