On treeings arising from HNN extensions
Yoshikata Kida
For certain HNN extensions including Baumslag-Solitar groups, a treeing is constructed from their certain probability-measure-preserving actions. This is a treeing of a quotient gr…
Groups with infinite FC-center have the Schmidt property
Yoshikata Kida, Robin Tucker-Drob
We show that every countable group with infinite FC-center has the Schmidt property, i.e., admits a free, ergodic, measure-preserving action on a standard probability space such th…
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…
Stable actions and central extensions
Yoshikata Kida
A probability-measure-preserving action of a countable group is called stable if its transformation-groupoid absorbs the ergodic hyperfinite equivalence relation of type II_1 under…
