摘要

Let C(B, N) be the free associative conformal algebra generated by a set B with a bounded locality N. Let S be a subset of C(B, N). A Composition-Diamond lemma for associative conformal algebras is first established by Bokut, Fong and Ke in 2004 [L. A. Bokut, Y. Fong and W.-F. Ke, Composition-Diamond Lemma for associative conformal algebras, J. Algebra 272 (2004) 739-774] which claims that if (i) S is a Grobner-Shirshov basis in C(B, N), then (ii) the set of S-irreducible words is a linear basis of the quotient conformal algebra C(B, N| S), but not conversely. In this paper, by introducing some new definitions of normal S-words, compositions and compositions to be trivial, we give a new Composition-Diamond lemma for associative conformal algebras, which makes the conditions (i) and (ii) equivalent. We show that for each ideal I of C(B, N), I has a unique reduced Grobner-Shirshov basis. As applications, we show that Loop Virasoro Lie conformal algebra and Loop Heisenberg-Virasoro Lie conformal algebra are embeddable into their universal enveloping associative conformal algebras.

KE,组成 - 金刚石引理用于关联共形代代数,J.代数272(2004)739-774,如果(i)是在C(B,N)中的Grobner-shirshov基础,那么(ii)集合S-Irreafucible单词是商品共形代代数C(B,N |)的线性基础,但不相反。在本文中,通过引入常规S型,组合物和组合物的一些新定义来微不足道,我们为缔合的共形代数提供了一种新的组合物 - 金刚石引理,这使得条件(i)和(ii)等同物。我们表明,对于C(B,N)的每个理想I,我有一个独特的Grebner-Shirshov基础。作为应用程序,我们展示了环路Virasoro Lie集合代数和Loop Heisenberg-Virasoro Lie保形代数被嵌入到其普遍包封的关联共形代代数中。
