Entropy and non-degeneracy of Enriques surfaces

Abstract: The entropy of an algebraic surface serves as an invariant that quantifies the complexity of its automorphism group. Recently, K3 surfaces with zero entropy have been classified by Brandhorst-Mezzedimi and Yu. ​​​​​In this talk, I will discuss joint work with Martin (Bonn) and Mezzedimi (Bonn) concerning the classification of Enriques surfaces with zero entropy. To conclude, I will propose a conjecture on the connection between zero entropy and the non-degeneracy invariant.
