Abstract

Consider a locally compact quantum group G\mathbb{G} with a closed classical abelian subgroup Γ\Gamma equipped with a 22-cocycle Ψ:Γ^×Γ^C\Psi:\hat{\Gamma}\times\hat{\Gamma}\to\mathbb{C}. We study in detail the associated Rieffel deformation GΨ\mathbb{G}^{\Psi} and establish a canonical correspondence between Γ\Gamma-invariant convolution semigroups of states on G\mathbb{G} and on GΨ\mathbb{G}^{\Psi}.
