Equivariant K-homology and K-theory for some discrete planar affine groups

Ramon Flores, Sanaz Pooya, Alain Valette

We consider the semi-direct products $G = Z^{2} ⋊ G L_{2} (Z), Z^{2} ⋊ S L_{2} (Z)$ and $Z^{2} ⋊ Γ (2)$ (where $Γ (2)$ is the congruence subgrou…

Higher Kazhdan projections, $ℓ_{2}$ -Betti numbers and Baum-Connes conjectures

Kang Li, Piotr W. Nowak, Sanaz Pooya

We introduce higher-dimensional analogs of Kazhdan projections in matrix algebras over group $C^{*}$ -algebras and Roe algebras. These projections are constructed in the framework of…

K-theory for the $C^{*}$ -algebras of the solvable Baumslag-Solitar groups

Sanaz Pooya, Alain Valette

We provide a new computation of the K-theory of the group $C^{*}$ -algebra of the solvable Baumslag-Solitar group $B S (1, n) (n \neq = 1)$ ; our computation is based on the Pimsner-Voicule…
