Invariant trace simplices and relative property (T)

Raz Slutsky

Let $I^\pm : G ↷ A$ be an action of a countable discrete group on a separable unital $C^{*}$ -algebra. We study the simplex $T (A)^{G}$ of $G$ -invariant traces an…

Betti Numbers of Negatively Curved Orbifolds with Coefficients in Arbitrary Fields

Guy Kapon, Raz Slutsky

We show that the Betti numbers of finite-volume negatively curved orbifolds grow at most linearly with the volume, with coefficients in an arbitrary field. In particular, this give…
