The p-semisimple property for some generalizations of BCI algebras and its applications

Lidia ObojskaAndrzej Walendziak — 2020

Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica

This paper presents some generalizations of BCI algebras (the RM, tRM, *RM, RM**, *RM**, aRM**, *aRM**, BCH**, BZ, pre-BZ and pre-BCI algebras). We investigate the p-semisimple property for algebras mentioned above; give some examples and display various conditions equivalent to p-semisimplicity. Finally, we present a model of mereology without antisymmetry (NAM) which could represent a tRM algebra.

Some Remarks on Rings

Commentationes Mathematicae

Algebraic structures such as Rings, Fields, Boolean Algebras (Set Theory) and σ -Fields are well known and much has been written about them. In this paper we explore some properties of rings related to the distribution law. Specifically, we shall show that for rings there exists only one distribution law. Moreover, for the ring ( Z p ( p 1 ) n + , · ) , where ( p , n ) = 1 there exist isomorphic groups ( G , + ) , ( H , · ) , G , H Z p ( p 1 ) n of the order ( p 1 ) . Finally, we note that every ring ( Z p n , + , · ) contains subfields mod ( p n ) .
