Keywords:
regular semigroup; inverse semigroup; e-variety; biinvariant congruence; bifree object
Summary:
A multiplication of e-varieties of regular $E$-solid semigroups by inverse semigroup varieties is described both semantically and syntactically. The associativity of the multiplication is also proved.
