报告简介：

Since the 1970s, the smallest known non-finitely based involution semigroups are of order six. Recently, we have found the first example of a non-finitely based involution semigroup of order five--the involution monoid $(A_0^1, ^{*})$. It is natural to question what is the smallest order of non-finitely based involution monoids. In this talk, it is shown that all involution semigroups of order four or less and all involution monoids of order five except $(A_0^1, ^{*})$ are finitely based. Therefore, involution monoid $(A_0^1, ^{*})$ is the only minimal non-finitely based involution monoids.
