Fano 4-folds with $b_{2} > 12$ are products of surfaces – Cinzia Casagrande (Università di Torino)

Archivio 22 March 2023 16:00 - 17:00 Department of Mathematics, Aula Magna.

Let $X$ be a smooth, complex Fano 4-fold, and $b_{2}$ its second Betti number. We will discuss the following result: if $b_{2} > 12$ , then X is a product of del Pezzo surfaces. The proof relies on a careful study of divisorial elementary contractions $f:…

Random iteration on hyperbolic Riemann surfaces – Marco Abate (University of Pisa)

Archivio 22 March 2023 16:00 - 17:00 CRM - SNS.

In this talk we shall describe the asymptotic behaviour of sequences of functions obtained by iteratively left-composing or right-composing holomorphic self-maps of a hyperbolic Riemann surface $X$ . We shall consider in detail two cases: when the…
