‘Decision problems for finitely presented and one-relation semigroups and monoids’
(with V. Maltcev)
International Journal of Algebra and Computation 19, no. 6 (September 2009), pp. 747–770.
For some distinguished properties of semigroups, such as having idempotents, regularity, hopficity etc, we study the following: whether that property or its negation is a Markov property, whether it is decidable for finitely presented semigroups and for one-relation semigroups and monoids. All the results and open problems are summarized in a table.
