Description
The Baum-Connes conjecture on the K-theory of group C*-algebras is a difficult open problem since the beginning of the 1980’s. In the last 30 years a programme has been developed to prove the Baum-Connes conjecture with coefficients for semi-simple Lie groups. The tools involved are: the flag manifolds, the BGG complex, and L2 cohomology of symmetric spaces.
