Comparison and vanishing theorems for K\"ahler manifolds

Differential Geometry 2022-07-18 v2

Abstract

In this paper, we consider orthogonal Ricci curvature RicRic^{\perp} for K\"ahler manifolds, which is a curvature condition closely related to Ricci curvature and holomorphic sectional curvature. We prove comparison theorems and a vanishing theorem related to these curvature conditions, and construct various examples to illustrate their subtle relationship.
