A disintegration theorem for non-second-countable etale groupoids

Sergey Neshveyev

The paper provides a self‑contained proof of a disintegration theorem for C*-algebras of possibly non‑Hausdorff étale groupoids that can be covered by countably many open bisection…

The ideal structure of Exel-Pardo algebras and their higher rank analogues

Johannes Christensen, Sergey Neshveyev

Given a pseudo-free self-similar action of a countable group on a countable directed graph with amenable stabilizers of the vertices, we identify the exact conditions under…

Kohn--Nirenberg quantization of the affine group and related examples

Pierre Bieliavsky, Victor Gayral, Sergey Neshveyev +1

We show how to construct unitary dual -cocycles for a class of semidirect products that exhibit many similarities with the affine group ${\rm Aff}(V)=\GL(V)\ltimes V$ of a finit…

Cartan subproduct systems

Suvrajit Bhattacharjee, Olof Giselsson, Sergey Neshveyev

Given a semisimple compact Lie group and a nonzero dominant integral weight , the highest weight -modules form a subproduct system of finite dimensional Hilb…

The ideal structure of C*-algebras of etale groupoids with isotropy groups of local polynomial growth

Johannes Christensen, Sergey Neshveyev

Given an amenable second countable Hausdorff locally compact étale groupoid such that each isotropy group has local polynomial growth, we give a desc…

Subproduct systems with quantum group symmetry. II

Erik Habbestad, Sergey Neshveyev

We complete our analysis of the Temperley-Lieb subproduct systems, which define quantum analogues of Arveson's -shift, by extending the main results of the previous paper to the…
