A rigid, not infinitesimally rigid surface with K ample
arXiv:2010.14371
Abstract
We produce an example of a rigid, but not infinitesimally rigid smooth compact complex surface with ample canonical bundle using results about arrangements of lines inspired by work of Hirzebruch, Kapovich and Millson, Manetti and Vakil.
