  • Abstract: Although bounded cohomology is a very useful invariant its computation is notoriously difficult. Even determining whether the bounded cohomology of a group vanishes or not is a very hard problem. In this talk I propose a geometric strategy to show that certain generalized knot groups have non-vanishing bounded cohomology.
