Abstract

In this paper an algebraic version for temporal algebras of the logical filtrations for modal and temporal logics is analysed. A structure theorem for free temporal algebras and also some results with regard to the variety of temporal algebras are obtained.

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

Assosymmetric algebras are nonassociative algebras, where xy z y x yz remains invariant under each permutation of x, y, z. In general, the free nonassociative algebra in a variety is difficult to describe. We show this is not the case for free assosymmetric algebras having characteristic /2, 3. We e
