AbstractIn this paper, the concept of the direct product of a group is studied from the classical settings. We then propose the notion of the direct product of a soft multigroup and investigate some of its structural properties. Finally, the concept of upper and lower cuts of soft multigroup is introduced, exemplified and some related results are established.

AbstractIn this article, we expose some new results about PMS-algebras. Thus, by connecting the concepts of subalgebras and ideals as well as ideals and right congruences in this class of logical algebras, we expand the paradigm related to PMS-algebras.

AbstractThe notion of AB-algebras was introduced in 2017 by Hameed and Abbas. Subsequently, this class of algebras was the subject of study by several authors. In this paper, in addition to giving an overview of some of the results and assertions about this class of logical algebras, we comment on a significant number of demonstrations of these assertions, and also state several new assertions and demonstrate their proofs.
