Let G be a group, F a field, and A a finite-dimensional central simple algebra over F on which G acts by F-algebra automorphisms. We study the subalgebras and ideals of A which are preserved by the group action. We prove a structure theorem and two classification theorems for invariant subalgebras u

We prove that if r 1 , . . . , r n are Euclidean reflections corresponding to a linearly independent set of vectors, then the group r 1 , . . . , r n is finite if and only if the natural Hurwitz braid group action on such ordered sets of reflections has finite orbit and we characterise the orbits fo

We extend a recent ergodic theorem of A. Nevo and E. Stein to the non-commutative case. Let \ be a faithful normal state on the von Neumann algebra A. Let [a i ] r i=1 generate F r , the free group on r generators, and let [: i ] r i=1 be V-automorphisms of A which leave \ invariant. Define , to be
