Stability of the Cotangent Bundle on Surfaces with Ample Canonical Class

Abstract

In this article, we study the Bridgeland stability of the cotangent bundle on K3 surfaces and surfaces with ample canonical class. On a surface $X$ with ample canonical class $K$, we find values $t_0>0$ such that the cotangent bundle is semistable with respect to the Bridgeland stability ${\sigma }_{tK}$ for all $t>t_0$. We also study special cases such as the fake projective planes and the fake quadrics.
