Finitely based monoids obtained from non-finitely based semigroups
Edmond W. H. Lee · NSUWorks (Nova Southeastern University) · 2013
Presently, no example of non-finitely based finite semigroup S is known for which the monoid S1 is finitely based. Based on a general result of M. V. Volkov, two methods are established from which examples of such semigroups can be constructed.
