Abstract

In this article, we prove the orbifold version of the Bogomolov-Gieseker inequality for stable Q\mathbb Q-sheaves on K\"ahler varieties, generalizing our earlier work \cite{GP25} in dimension three. We also provide a characterization of the equality case, a new purely analytical proof of the numerical characterization of complex torus quotients as well as a novel, complex analytic interpretation of the second orbifold Chern class associated to a Q\mathbb Q-sheaf.
