Chern number identities on compact complex surfaces and applications

Differential Geometry 2025-08-18 v1

Abstract

In this paper, we establish Chern number identities on compact complex surfaces. As an application, we prove that if (M,g)(M,g) is a compact Riemannian four-manifold with constant scalar curvature and admits a compatible complex structure JJ such that the complexified Ricci curvature is a non-positive (1,1)(1,1) form, then MM is a K\"ahler surface.
