 Bogomolov–Miyaoka–Yau inequality

The Bogomolov–Miyaoka–Yau inequality is an important result in algebraic geometry and complex geometry, particularly in the study of the geometry of algebraic varieties and the properties of their canonical bundles. The inequality pertains to smooth projective varieties (or algebraic varieties) of certain dimensions and relates the Kodaira dimension and the Ricci curvature.
