Free 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 Semigroups Whose Idempotent-Generated Subsemigroup is Aperiodic
In this paper, all semigroups are assumed to be finite unless otherwise stated. If H is a pseudovariety of groups (that is, a class of groups closed under formation of finite direct products, subgroups and quotients groups), then it is natural to define a group to be Hsolvable if it has a subnormal series each of whose quotients belongs to H. For instance a group is solvable in the classical se...
متن کاملOn Maximal Subgroups of Free Idempotent Generated Semigroups
We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup. (3) Every group is a maximal subgroup of some free regular idempotent generated semigroup. (4) Every finite group is a maximal subgroup of some free...
متن کاملIdempotent Measures on Compact Semigroups
Throughout this paper, 5 will be a compact Hausdorff topological semigroup, 5 will denote the convolution semigroup of normalized non-negative regular Borel measures on 5, and H will be the carrier of a measure p in 5. The space of continuous complex valued functions on 5 will be denoted by C(S), while Cr(S) will be the subspace of C(S) of real valued functions. Standard terminology and definit...
متن کاملSubgroups of Free Idempotent Generated Semigroups: Full Linear Monoids
We develop some new topological tools to study maximal subgroups of free idempotent generated semigroups. As an application, we show that the rank 1 component of the free idempotent generated semigroup of the biordered set of a full matrix monoid of size n×n,n > 2 over a division ring Q has maximal subgroup isomorphic to the multiplicative subgroup of Q.
