By the van Est isomorphism, continuous cohomology of simple Lie groups vanishes in degree greater than the dimension of the associated symmetric space. In his ICM address 2006, Monod conjectured that a similar vanishing theorem should hold for continuous bounded cohomology. In this talk we will present an approach to this conjecture in the case of SL_2®, applying methods from harmonic analysis and partial differential equations. This is joint work with T. Hartnick.
