On outer automorphisms of certain graph $C^{*}$ -algebras

Swarnendu Datta, Debashish Goswami, Soumalya Joardar

Given a countable abelian group $A$ , we construct a row finite directed graph $Γ (A)$ such that the $K_{0}$ -group of the graph $C^{*}$ -algebra $C^{*} (Γ (A))$ …

Metrics on $C^{*}$ -algebras of Étale groupoids from length functions

Arnab Chattopadhyay, Md Amir Hossain, Soumalya Joardar

We show that for an étale groupoid with compact unit space, the natural Dirac type operator from a continuous length function produces a natural pseudo-metric on the state space of…
