Abstract :
In this paper we extended the results of paper “On Closed Homotypical Varieties of Semigroups” and have shown that the homotypical varieties of semigroups defined by the identities axy = xnayx, axy = xanya[axy = yaynx], axy = xayan[axy = ynayx] and axy = xayxn are closed in itself, where (n ∈ N).
