Inner amenable groupoids and central sequences
Yoshikata Kida, Robin Tucker-Drob
We introduce inner amenability for discrete p.m.p. groupoids and investigate its basic properties, examples, and the connection with central sequences in the full group of the grou…
OE and W* superrigidity results for actions by surface braid groups
Ionut Chifan, Yoshikata Kida
We show that several important normal subgroups of the mapping class group of a surface satisfy the following property: any free, ergodic, probability measure preserving action…
Primeness results for von Neumann algebras associated with surface braid groups
Ionut Chifan, Yoshikata Kida, Sujan Pant
In this paper we introduce a new class of non-amenable groups denoted by which give rise to von Neumann algebras. Th…
W*-superrigidity for arbitrary actions of central quotients of braid groups
Ionut Chifan, Adrian Ioana, Yoshikata Kida
For any let be the quotient of the braid group through its center. We prove that any free ergodic probability measure preserving (pmp)…
