自由准李代数中的对称运算是岩浆性的

The symmetric operation in a free pre-Lie algebra is magmatic

Nantel Bergeron, Jean-Louis Loday

摘要:

预李积是一种二元运算,其结合子在最后两个变量中是对称的。因此,它的反对称化是一个李括号。本文研究预李积的对称化。我们表明,它不满足任何其他普遍的关系比交换性。这意味着从自由交换岩浆代数到自由预李代数的映射是由预李积的对称化所诱导的单射映射。这个结果与结合的情况相反,在结合的情况下,对称化产生了约当代数的概念。我们首先给出一个完备的证明。然后利用树型和双代数的性质给出了一个证明。

英文摘要:

A pre-Lie product is a binary operation whose associator is symmetric in the last two variables. As a consequence its antisymmetrization is a Lie bracket. In this paper we study the symmetrization of the pre-Lie product. We show that it does not satisfy any other universal relation than commutativity. It means that the map from the free commutative-magmatic algebra to the free pre-Lie algebra induced by the symmetrization of the pre-Lie product is injective. This result is in contrast with the associative case, where the symmetrization gives rise to the notion of Jordan algebra. We first give a self-contained proof. Then we give a proof which uses the properties of dendriform and duplicial algebras.
