Abstract

We introduce -algebras associated to the foliation structure of a quantum flag manifold. We use these to construct -equivariant Fredholm modules for the full quantum flag manifold of , based on an analytical version of the Bernstein-Gelfand-Gelfand complex. As a consequence we deduce that the flag manifold satisfies Poincaré duality in equivariant -theory. Moreover, we show that the Baum-Connes conjecture with trivial coefficients holds for the discrete quantum group dual to .
