Title: Cauchy-Bienaymé-Galton-Watson

The seminar will take place at Zoom

Abstract: We will be interested in the structure of large random Bienaymé-Galton-Watson trees, with critical offspring distribution belonging to the domain of attraction of a Cauchy law. We will identify a so-called condensation phenomenon, where a single vertex with macroscopic degree emerges.
