Abstract

A class of semirings, so called p-semirings, characterized by a natural number p is introduced and basic properties are investigated. It is proved that every p-semiring is a union of skew rings. It is proved that for some p-semirings with non-commutative operations, this union contains rings which are commutative and possess an identity. 

Keywords and phrases: semiring, p-semiring, p-semigroup, anti-inverse semigroup, union of rings, skew ring.
