Finite basis problem for involution semigroups of order four

Meng Gao, Wen Ting Zhang, Yan Feng Luo

Recently, we have found a non-finitely based involution semigroup of order five. It is natural to question what is the smallest order of non-finitely based involution semigroups. I…

Characterization of Cross varieties of -trivial monoids

Sergey V. Gusev, Edmond W. H. Lee, Wen Ting Zhang

A finitely based, finitely generated variety with finitely many subvarieties is a Cross variety. In the present article, it is shown that a variety of -trivial monoids is Cross…
