Groupoid Models of $C^{*}$ -algebras and Gelfand Duality

Kyle Austin, Atish Mitra

We construct a large class of morphisms, which we call partial morphisms, of groupoids that induce $*$ -morphisms of maximal and minimal groupoid $C^{*}$ -algebras. We show that the as…

Cohomological dimension with respect to nonabelian groups

Atish Mitra

Cencelj and Dranishnikov showed that for certain nilpotent groups $G$ , $K (G_{ab}, 1) \in AE (X)$ is equivalent to $K (G, 1) \in AE (X)$ for any compacta $X$ (here $G_{ab}$ …
