Admissible Higson-Roe sequences for transformation groupoids
Moulay-Tahar Benameur, Victor Moulard
Given a finitely generated discrete group Î, we construct for any admissible crossed product completion and for any metrizable finite dimensional compact Î-space X, a universal H…

The higher fixed point theorem for foliations. Applications to rigidity and integrality
Moulay Tahar Benameur, James L. Heitsch
We give applications of the higher Lefschetz theorems for foliations of [BH10], primarily involving Haefliger cohomology. These results show that the transverse structures of folia…

Higher relative index theorems for foliations
Moulay Tahar Benameur, James L. Heitsch
In this paper we solve the general case of the cohomological relative index problem for foliations of non-compact manifolds. In particular, we significantly generalize the groundbr…
