Abstract

It is shown that the transformation monoid [Formula: see text] is finitely based and a finite identity basis for [Formula: see text] is given, which solves the finite basis problem for [Formula: see text]. It is also shown that the variety Var[Formula: see text] generated by [Formula: see text] for which xyx is not an isoterm has uncountably many subvarieties, which gives an affirmative answer to a question of Jackson.
