Infinitesimal deformation, local deformation, and rigidity of tangent bundle of complex two ball quotients



In this talk, we study the problem of deformation rigidity of the holomorphic tangent bundle of a compact complex two ball quotient. This is in turn used to study a problem of Kodaira and Morrow about the distinction between infinitesimal and local deformation.
