Composition-Diamond lemma for associative $n$-conformal algebras

Abstract

In this paper, we study the concept of associative $n$-conformal algebra over a field of characteristic 0 and establish Composition-Diamond lemma for a free associative $n$-conformal algebra. As an application, we construct Gr\"{o}bner-Shirshov bases for Lie $n$-conformal algebras presented by generators and defining relations.
