INNER AMENABLE GROUPOIDS AND CENTRAL SEQUENCES
INNER AMENABLE GROUPOIDS AND CENTRAL SEQUENCES
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 groupoid or central sequences in the von Neumann algebra associated with the groupoid. Among other things, we show that every free ergodic p.m.p. compact …
