Quantization of locally compact groups associated with essentially bijective $1$ -cocycles

Pierre Bieliavsky, Victor Gayral, Sergey Neshveyev +1

Given an extension $0 \to V \to G \to Q \to 1$ of locally compact groups, with $V$ abelian, and a compatible essentially bijective $1$ -cocycle $η : Q \to V^$ , we define a dual uni…

Isotropy fibers of ideals in groupoid C $^{*}$ -algebras

Johannes Christensen, Sergey Neshveyev

Given a locally compact étale groupoid and an ideal $I$ in its groupoid C $^{*}$ -algebra, we show that $I$ defines a family of ideals in group C $^{*}$ -algebras of the isotropy groups an…

Cocycle twisting of semidirect products and transmutation

Erik Habbestad, Sergey Neshveyev

We apply Majid's transmutation procedure to Hopf algebra maps $H \to C [T]$ , where $T$ is a compact abelian group, and explain how this construction gives rise to braided Ho…
