Von Neumann algebras arising from Bost-Connes type systems
Sergey Neshveyev
We show that the KMS_beta-states of Bost-Connes type systems for number fields in the region 0<beta\le 1, as well as of the Connes-Marcolli GL_2-system for 1<beta\le 2, have type I…

Symmetric invariant cocycles on the duals of q-deformations
Sergey Neshveyev, Lars Tuset
We prove that for q not a nontrivial root of unity any symmetric invariant 2-cocycle for a completion of Uq(g) is the coboundary of a central element. Equivalently, a Drinfeld twis…
