$C^{*}$ -uniqueness Results for Groupoids

Are Austad, Eduard Ortega

For a second-countable locally compact Hausdorff étale groupoid $G$ with a continuous $2$ -cocycle $σ$ we find conditions that guarantee that $ℓ^{1} (G, σ)$ has…

Spectral invariance of $*$ -representations of twisted convolution algebras with applications in Gabor analysis

Are Austad

We show spectral invariance for faithful $*$ -representations for a class of twisted convolution algebras. More precisely, if $G$ is a locally compact group with a continuous $2$ -co…
