AbstractConsider a non-uniruled smooth projective surface S. We establish that the tangent bundle T_S is pseudo-effective if and only if the canonical divisor K_S is nef, and the second Chern class c_2(S) vanishes. Additionally, I will discuss the blow-up of a non-rational ruled surface with a pseudo-effective tangent bundle. This talk is based on a collaborative project with Yongnam Lee and Gu...
