Finitely based monoids
WebJul 2, 2024 · Stalactic, taiga, sylvester and Baxter monoids arise from the combinatorics of tableaux by identifying words over a fixed ordered alphabet whenever they produce the same tableau via some insertion algorithm. In this paper, three sufficient conditions under which semigroups are finitely based are given. By applying these sufficient conditions, it … 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.

WebFeb 21, 2014 · We present a general method for proving that a semigroup is non-finitely based. The method is strong enough to cover the non-finite basis arguments in articles [1,3,4,5,7,8, 11,14,16,21,27,31,36,37]. In particular, the method allows to generalize the results in [1,8,36,37] and to simplify their proofs. The method also allows to remove one …
