Bands of Semigroups
In studying a general semigroup S, a natural thing to do is to decompose 5 (if possible) into the class sum of a set {Sa; aCl} of mutually disjoint subsemigroups Sa such that (1) each Sa belongs to some more or less restrictive type 13 of semigroup, and (2) the product SaSfi of any two of them is wholly contained in a third: SaSpClSy, for some yCI depending upon a and /3. We shall then say that...
متن کاملRadicals Commuting with Bands of Semigroups
It is known that ring and semigroup theories have evolved many similar methods. The exchange of ideas between these theories has enriched both of them. Among ring concepts transfered to semigroups, the notion of a radical deserves mentioning. The analogy with radicals of rings suggests that semigroup radicals may be applicable in studying the structure of semigroups. On the other hand, many str...
متن کاملFree Idempotent Generated Semigroups over Bands
We study the general structure of the free idempotent generated semigroup IG(B) over an arbitrary band B. We show that IG(B) is always a weakly abundant semigroup with the congruence condition, but not necessarily abundant. We then prove that if B is a normal band or a quasi-zero band for which IG(B) satisfies Condition (P ), then IG(B) is an abundant semigroup. In consequence, if Y is a semila...
متن کاملOn Completely Simple Semigroups
In this paper completely simple semigroups or generalized groups are considered. We characterize generalized groups which are normal generalized groups. Homomorphisms of generalized groups are considered. Equivalent conditions for the kernel of a homomorphism are deduced. We prove that the group components of a generalized group have the same cardinality. We also prove that if G is a finite nor...
متن کاملMatrix Representations of ¿-simple Semigroups
By a 'representation' we shall mean throughout a representation by n x n matrices with entries from an arbitrary (commutative) field. Clifford has constructed all representations of completely simple semigroups [1; 4]. Munn has determined the representations of finite semigroups for which the corresponding semigroup algebra is semi-simple [6]. It is noted by Clifford and Preston [4] that if S i...
