Maximal subgroups of amalgams of finite inverse semigroups

, 2013
We use the description of the Schützenberger automata for amalgams of finite inverse semigroups given by Cherubini et al. (J. Algebra 285:706–725, 2005) to obtain structural results for such amalgams.

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.

Normally Ordered Inverse Semigroups

Semigroup Forum, 1998
Let \(S\) be an inverse semigroup and \(E\) the set of its idempotents. Suppose that there exists a partial order \(\ll\) on \(E\) such that two idempotents are \(\ll\)-comparable if and only if they belong to the same \(\mathcal J\)-class of \(S\) and, for all \(s\in S\) and \(e,f\in Ess^{-1}\), \(e\ll f\) implies \(s^{-1}es\ll s^{-1}fs\).

RELATIVELY FREE INVERSE SEMIGROUPS

The Quarterly Journal of Mathematics, 1986
In [Trans. Am. Math. Soc. 294, 243--262 (1986; Zbl 0602.20052)] \textit{N. R. Reilly} and the author studied the semigroups in the title, with respect to such properties as being E-unitary, fundamental, combinatorial and completely semisimple. This paper continues that study. Let \(\mathcal V\) be a variety of inverse semigroups: then \(F\mathcal V_X\)

Inverse Near Permutation Semigroups

Semigroup Forum, 2004
The symbol \({\mathcal T}_N\) denotes the semigroup, under composition, of all selfmaps of a set \(X\) with \(N\) elements. The `rank' of an element \(\alpha\in{\mathcal T}_N\) is defined to be \(|X\alpha|\). A subsemigroup of \({\mathcal T}_N\) is defined to be a `near permutation semigroup' if it is generated by a group \(G\) of permutations together
