On equations in inverse semigroups

Algebra Universalis, 2002
It is shown for an inverse semigroup \(\mathcal S\) which is not a group, the system \(x_1=x_2\) and \(x_3=x_4\) of equations in \(\mathcal S\) is not equivalent to any equation as well as the disjunction \(x_1=x_2\) or \(x_3=x_4\).

On the Structure of Inverse Semigroup Amalgams

International Journal of Algebra and Computation, 1997
This paper is the second of two papers devoted to the study of amalgamated free products of inverse semigroups. We use the characterization of the Schützenberger automata given previously by the author to obtain structural results and preservational properties of lower bounded amalgams.

IDENTITIES OF FINITE INVERSE SEMIGROUPS

International Journal of Algebra and Computation, 1993
Inverse semigroups are considered as algebras with two operations: multiplication and inversion. We prove that there are no inherently non-finitely based finite inverse semigroups. In constrast, if we consider inverse semigroups as semigroups (one binary operation) then it was proved by the author that almost all finite inverse semigroups are ...

Inverse semigroups

1995
Abstract In planning the chapter on inverse semigroups the main problem has been one of selection. As long ago as 1961, Clifford and Preston offered the opinion that inverse semigroups were the most promising class of semigroups for future study, and the intervening years have amply justified their forecast.
