摘要

为交换单元上的次直接不可还原 S 行为类找到了一个公理化标准。作为推论，我们提出了一些性质，只要交换单元上的次直接不可还原行为类是可公理化的，那么交换单元就应该满足这些性质。关于子直接不可还原行为类可公理化的单元的完整描述问题，即使对于换元单元来说，也仍然是一个悬而未决的问题。

Axiomatizability of the Class of Subdirectly Irreducible S-Acts over a Commutative Monoid

An axiomatizability criterion is found for the class of subdirectly irreducible S-acts over a commutative monoid. As a corollary, a number of properties are presented which a commutative monoid should satisfy provided that the class of subdirectly irreducible acts over it is axiomatizable. The question about a complete description of monoids over which the class of subdirectly irreducible acts is axiomatizable remains open even for the case of a commutative monoid.

期刊介绍： This bimonthly journal publishes results of the latest research in the areas of modern general algebra and of logic considered primarily from an algebraic viewpoint. The algebraic papers, constituting the major part of the contents, are concerned with studies in such fields as ordered, almost torsion-free, nilpotent, and metabelian groups; isomorphism rings; Lie algebras; Frattini subgroups; and clusters of algebras. In the area of logic, the periodical covers such topics as hierarchical sets, logical automata, and recursive functions. Algebra and Logic is a translation of ALGEBRA I LOGIKA, a publication of the Siberian Fund for Algebra and Logic and the Institute of Mathematics of the Siberian Branch of the Russian Academy of Sciences. All articles are peer-reviewed.
