On second cohomology of duals of compact groups
Sergey Neshveyev, Lars Tuset
We show that for any compact connected group G the second cohomology group defined by unitary invariant 2-cocycles on \hat G is canonically isomorphic to H^2(\hat{Z(G)};T). This im…
Traces on crossed products
Sergey Neshveyev
We give a description of traces on C(X)\rtimes G in terms of measurable fields of traces on the C*-algebras of the stabilizers of the action of G on X.
Type III_1 equilibrium states of the Toeplitz algebra of the affine semigroup over the natural numbers
Marcelo Laca, Sergey Neshveyev
We complete the analysis of KMS-states of the Toeplitz algebra of the affine semigroup over the natural numbers, recently studied by Raeburn and the first author, by showing that f…
Bost-Connes systems, Hecke algebras, and induction
Marcelo Laca, Sergey Neshveyev, Mak Trifkovic
We consider a Hecke algebra naturally associated with the affine group with totally positive multiplicative part over an algebraic number field K and we show that the C*-algebra of…
