Description	A countable group is said to have the Schmidt property if it admits an ergodic free p.m.p. action such that the full group of the associated orbit equivalence relation contains a non-trivial central sequence. It was originally asked by Klaus Schmidt whether any inner amenable group has this property. We show that any countable group with infinite FC-center has the Schmidt property, and as its consequence, any inner amenable, property (T) group has the Schmidt property. This is a joint work with Robin Tucker-Drob.
