On fullness of von Neumann algebras associated with non-singular Borel equivalence relations

Abstract

It is shown by Houdayer-Isono that a group measure space von Neumann algebra is a full factor if the group is countable discrete and bi-exact, and the action is strongly ergodic, essentially free and non-singular. Recently, bi-exactness for locally compact groups was introduced by Brothier-Deprez-Vaes. In this paper, we will show that Houdayer-Isono type result holds for bi-exact locally compact groups.
