TL;DR: For elements of a finite inverse semigroup, an equivalence relation called p-conugacy was introduced in this paper, where it was shown that the character of the representation of a matrix representation of such a matrix over the field of complex numbers is equal to the number of classes of pconjugate elements.
Abstract: For elements of a finite inverse semigroup, an equivalence relation called p-conugacy is introduced. It is proved that for any matrix representation of a finite inverse semigroup the values of the character of the representation are equal on p-conjugate elements. The number of inequivalent irreducible matrix representations of a finite inverse semigroup over the field of complex numbers is equal to the number of classes of p-conjugate elements.

01 Jan 1996TL;DR: In this article, the semigroup structure of the syntactic monoid Syn(C+) of a maximal prefix code C+ is investigated and it is shown that Syn has a kernel J which is a right group.
Abstract: In this paper we investigate the semigroup structure of the syntactic monoid Syn(C+) of C+, the semigroup generated by a maximal prefix code C for which C+ is a single class of the syntactic congruence. In particular we prove that for such a prefix code C, either Syn(C+) is a group or it is isomorphic to a special type of submonoid of G× T (R) where G is a group and T (R) is the full transformation semigroup on a set R with more than one element. From this description we conclude that Syn(C+) has a kernel J which is a right group. We further investigate separately the case when J is a right zero semigroup and the case when J is a group.
