## 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.

✦ Synopsis
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 exhibit a natural basis, describe how basis elements are multiplied and show how arbitrary elements can be expressed relative to this basis.

The aim of this paper is to prove a conjecture due to Y. Lyubich, according to which a nuclear Bernstein algebra with a stochastic basis is regular.
Let L be an arbitrary Lie algebra. Then by Cohn's Theorem its universal Ž . enveloping algebra can be embedded in a skew field D L . We study this skew Ž . field in the case when L is a free Lie algebra and prove that in this case D L is Ž . isomorphic to the universal field of fractions for the fre
## Abstract We prove that the __m__ ‐generated free MV‐algebra is isomorphic to a quotient of the disjoint union of all the __m__ ‐generated free MV^(__n__)^‐algebras. Such a quotient can be seen as the direct limit of a system consisting of all free MV^(__n__)^‐algebras and special maps between th
