WebAug 1, 2024 · We invoke Dyck’s Theorem (see, e.g., [ 8, Theorem III.8.3]). Specialized in the case of monoids, it says that if M is a monoid generated by a set A subject to relations R and N is a monoid generated by A and such that all the relations R hold in N, then N is a homomorphic image of M.
WebJun 6, 1999 · Given a Dyck path one can define its area as the area of the region enclosed by it and the x-axis. The following results are known: Theorem 1 (Merlini et al. [3]).
