Theorem 1.51 (Jackson and Lee 2024, Theorem 4.3) A finite monoid is inherently non-finitely based in the monoid signature if and only if it is inherently non-finitely based in the semigroup signature.
WebIs the property of being finitely presented a quasi-isometry invariant for the class of all monoids? This question is posed by Gray and Kambites in [7, Question 1].It is well known that the answer is positive for groups [3, Proposition I.8.24], and Gray and Kambites also establish it for monoids with finitely many left- and right ideals [7, Theorem 4], and for … 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 …

WebFeb 18, 2014 · We present a method for proving that a semigroup is finitely based and find some new sufficient conditions under which a monoid is finitely based. As an application, we find a class of finite monoids where the finite basis property behaves in a complicated way with respect to the lattice operations but can be recognized by a simple algorithm. …

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. shannon rose clifton menu
