Maximal Clifford Semigroups of Matrices

open access: yes, 2006
All maximal Clifford semigroups of matrices are identified up to isomorphism. If the ground field of the matrices is finite, then there exists a unique Clifford semigroup of maximum ...

On a Conjecture Concerning Semigroup Homomorphisms

open access: yes, 1970
In this paper we settle (with a counterexample) the question raised by Clifford and Preston in [2, p. 275], concerning maximal group homomorphic images of semigroups.

Ideals and finiteness conditions for subsemigroups

open access: yes, 2013
In this paper we consider a number of finiteness conditions for semigroups related to their ideal structure, and ask whether such conditions are preserved by sub- or supersemigroups with finite Rees or Green index. Specific properties under consideration

Topological and differentiable aspects of Clifford semigroups

open access: yes
This paper investigates the interplay between algebraic structure, topology, and differentiability in Clifford semigroups. The study is developed along three main themes. First, in the compact Hausdorff setting, we provide an explicit construction of a compatible metric for the Bowman topology.

Constituent groups of Clifford semigroups arising from t-closure

open access: yes, 2009
The t-class semigroup of an integral domain R, denoted St(R), is the semigroup of fractional t-ideals modulo its subsemigroup of nonzero principal ideals with the operation induced by ideal t-multiplication.

Class semigroups of integral domains

open access: yes, 2003
This paper seeks ring-theoretic conditions of an integral domain R that reflect in the Clifford property or Boolean property of its class semigroup S(R), that is, the semigroup of the isomorphy classes of the nonzero (integral) ideals of R with the ...
