Extends previous findings on homotypical varieties of semigroups, demonstrating their closure properties.
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).
