In this talk I will describe a cohomological formula for a higher
index pairing between invariant elliptic differential operators and
differentiable group cohomology classes. This index theorem generalizes the
Connes-Moscovici L^2-index theorem and its variants. This is joint work with
Markus Pflaum and Hessel Posthuma.
