报告摘要：First studied in the 70's in the context of Banach algebras, the theory of bounded cohomology was then widely generalised by Gromov, who converted it into a powerful tool to study groups and spaces. It is by now a well-established invariant, but on its flip side it is often difficult to compute and, beyond the case of amenable groups, many questions remain widely open.

I will introduce the basics of bounded cohomology of groups and its main properties, before turning to recent results obtained with Francesco Fournier-Facio, Yash Lodha and Marco Moraschini: a new algebraic condition that implies the vanishing of the bounded cohomology of a given group for a big family of coefficient modules. This condition is satisfied by many non-amenable groups of topological, geometric or algebraic origin.
