Furstenberg entropy of boundaries and their spectra
***Attention cette séance du séminaire aura lieu dans le bâtiment 36, salle 106 *** In this talk I will give a gentle introduction to Furstenberg entropy of some specific dynamical systems and show a way to view this entropy as a function on the space of invariant sub-σ-algebras. Moreover, for certain groups, I will explain how the entropy spectra look like. This is a joint work with M. Björklund and Y. Hartman.
