报告摘要:Median spaces have recently begun to play an increasingly significant role in geometric group theory. In this talk, I will explain how to use Bader-Furman’s dynamical approach to study cocycle superrigidity for finite-rank median spaces, thereby providing a novel proof of superrigidity for homomorphisms. This talk is based on joint work with Lamine Messaci.
