Configuration Spaces The n-th ordered configuration space C˜ n (M ) of a space M is the space of all n-tupels (ζ1 , . . . , ζn ) of distinct points in M ; and the quotient C n (M ) = C˜ n (M )/Sn by the free action o

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

1 Abstract A countable group Γ is called shift-minimal if every non-trivial measure preserving action of Γ weakly contained in the Bernoulli shift Γ y ([0, 1]Γ , λΓ ) is free. We show that any group Γ whose reduc
