摘要

诺维科夫共形代数是一种共形代数,它的系数代数是右对称和左交换的(即它是一个 "普通 "的诺维科夫代数)。我们证明,每一个在生成子集上具有均匀有界局部函数的诺维科夫共形代数,都可以嵌入到一个具有导数的交换共形代数中。特别是,每个无限生成的诺维科夫共形代数都有一个交换共形差分包络。对于无限生成的代数,这一说法一般不成立。

Differential envelopes of Novikov conformal algebras
A Novikov conformal algebra is a conformal algebra such that its coefficient algebra is right-symmetric and left commutative (i.e., it is an ``ordinary'' Novikov algebra). We prove that every Novikov conformal algebra with a uniformly bounded locality function on a set of generators can be embedded into a commutative conformal algebra with a derivation. In particular, every finitely generated Novikov conformal algebra has a commutative conformal differential envelope. For infinitely generated algebras this statement is not true in general.
