Semilattice ordered inverse semigroups -- 15. Isomorphism problems for transformation semigroups -- 16. On McAlister's Monoid and its contracted algebra -- 17. Relative monoid presentations and finite derivation type -- 18. Literal varieties and pseudovarieties of homomorphisms onto Abelian groups -- 19. Factorizability in certain classes over inverse semigroups Summary This festschrift volume in honour of Donald B McAlister on the occasion of his 65th birthday presents papers from leading researchers in semigroups and formal languages. The contributors cover a number of areas of current interest: from pseudovarieties and regular languages to ordered groupoids and one-relator groups, and from semigroup algebras to presentations of monoids and transformation semigroups. The papers are accessible to graduate students as well as researchers seeking new directions for future work Notes Title from e-book title screen (viewed Dec. 12, 2008) Bibliography Includes bibliographical references Notes English Subject McAlister, Donald B., 1940- SUBJECT McAlister, Donald B., 1940- fast Subject Semigroups -- Congresses Formal languages -- Congresses Formal languages Semigroups Genre/Form Conference papers and proceedings Form Electronic book Author André, Jorge M Universidade de Lisboa.
