✦ Synopsis


Given an algebra A, p.(A) denotes the number of distinct n-ary term operations t :A" ~ A of A which depend on all n variables. We solve some problems of Berman, Gr~itzer and Kisielewicz concerning the sequence (po(A),pl(A) ..... p.(A) .... ) in case [A I is finite. Our methods yield new results about totally symmetric functions on a finite set.

We show that it is decidable for any given ground term rewrite systems R and S if there is a ground term rewrite system U such that If the answer is yes, then we can e ectively construct such a ground term rewrite system U .

We give a natural extension of the notion of the contragredient module for a vertex operator algebra. By using this extension we prove that for regular vertex Ε½ operator algebras, Zhu's C -finiteness condition holds, fusion rules for any three 2 . irreducible modules are finite and the vertex operat
