MIXING ACTIONS OF COUNTABLE GROUPS ARE ALMOST FREE ROBIN D. TUCKER-DROB A measure preserving action of a countably innite group Γ is called totally ergodic if every innite subgroup of Γ acts ergodically. For example,

Abstract This note answers a question of Kechris: if H < G is a normal subgroup of a countable group G, H has property MD and G/H is amenable and residually finite then G also has property MD. Under the same hypothesis w
