The Baum-Connes conjecture and linear group actions on spaces of finite asymptotic dimension

The Baum-Connes conjecture describes the K-theory of a reduced crossed product of a C *-algebra by a group G in terms of the K-homology of the classifying space of proper actions of G. We shall describe the Conjecture for discrete group case and its connotations. Commenting on results of Guentner, Higson, Kasparov, Weinberger, and Yu, we investigate the possibility of applying a finite-dimensionality argument in order to prove parts of the Conjecture for discrete linear groups.

Hausdorff dimension for an open class of repellers in 2

We compute the Hausdorff dimension for an open class of Iterated Function Schemes in 2 in the C 2 topology, in terms of the pressure function. This class is characterized by a domination condition that is not too strong, plus the non-overlapping condition. Also in this class there exists a unique invariant probability measure of full Hausdorff dimension. Finally we show that the Hausdorff dimension is a continuous function in this class.
