Let S be a regular semigroup. A pair (e,f) of idempotents of S is said to be a skew pair of idempotents if fe is idempotent, but ef is not. T. S. Blyth and M. H. Almeida (T. S. Blyth and M. H. Almeida, skew pair of idempotents in transformation semig

Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S, , is called an (m, n)-ideal of S if (i) Am SAn A, and (ii) if x A, y S such that y x, then y A. In this paper, necessary and sufficient cond

Let τ be a type of algebras. This paper introduces special terms of type τ called terms of a fixed variable. It turns out that the set of all terms of a fixed variable of type τ forms the many-sorted clone satisfying the superassociative law as id

Let P 2 ⊂ P 1 be a pair of weakly semiprime ideals of an ordered semigroup ( S , · , ≤ ) . Then, the pair P 2 ⊂ P 1 is called a weakly semiprime segment of S if ⋂ n ∈ N I n ⊆ P 2 for all ideals I of S such that P 2 ⊂ I ⊂ P 1 . In thi
