On topologically trivial automorphisms of compact Kähler manifolds and algebraic surfaces
arXiv:2012.11272
Abstract
In this paper, we investigate automorphisms of compact Kähler manifolds with different levels of topological triviality. In particular, we provide several examples of smooth complex projective surfaces X whose groups of -isotopically trivial automorphisms, resp. cohomologically trivial automorphisms, have a number of connected components which can be arbitrarily large.
