چکیده انگلیسی
We continue our investigations on algebras R over a field K with generators x1,x2,â¦,xn subject to (n2) quadratic relations of the form xixj=xkxl with (i,j)â (k,l) and, moreover, every monomial xixj appears at most once in one of the defining relations. If these relations are non-degenerate then it is shown that the underlying monoid S contains an abelian submonoid A=ãsN|sâSã, that is finitely generated and that S=âfâFfA=âfâFAf for some finite subset F of S. So, R=K[S] is a finite module over the Noetherian commutative algebra K[A]; in particular R is a Noetherian algebra that satisfies a polynomial identity. Well-known examples of such monoids are the monoids of I-type that correspond to non-degenerate set-theoretical solutions of the Yang-Baxter equation. We show that S is of I-type if and only if S is cancellative and satisfies the cyclic condition. Furthermore, if S satisfies the cyclic condition, then S is cancellative if and only of K[S] is a prime ring. Moreover, in this case, one can replace the monoid A by a finitely generated submonoid Aâ² such that fAâ²=Aâ²f, for each fâF; in particular R=K[S] is a normalizing extension of K[Aâ²] and thus the prime ideals of K[S] are determined by the prime ideals of K[Aâ²]. These investigations are a continuation and generalization of earlier results of Cedó, Gateva-Ivanova, Jespers and OkniÅski in the case the defining relations are square free.
