Bounded cohomology was introduced by Johnson and Trauber in the context of Banach algebras and has since become a widely studied group invariant. In this talk, we give an introduction to the bounded cohomology of groups, focusing particularly on its vanishing properties. We define the wreath product construction and see some properties of the resulting groups. Finally, we will present a proof of Monod’s vanishing result for the bounded cohomology of (restricted) wreath products.
