WebThe main goal of this paper is to prove that the involution monoid (C 3, *) is non-finitely based. Therefore, in contrast, combining with previous results yields that the involution Catalan monoid (C n, *) is finitely based if and only if n = 1. The Kiselman monoid K n generated by n elements is also considered.
