Description
Numerically and cohomologically trivial automorphisms form a classical topic
in algebraic geometry, especially for algebraic surfaces. I will focus on the
case of complex elliptic surfaces of Kodaira dimension one, which features
some surprising results, also in view of past claims. Much of this will be
motivated by the instructive case of Enriques surfaces.
