of Enriques surfaces<br>
<br>
</font></font></b></b></div>
</div>
<div align="left"><b><b><font color="#ff0000">Abstract:
</font></b></b>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.<br>
