预交错代数与预交错双代数

Pre-alternative algebras and pre-alternative bialgebras

Xiang Ni, Chengming Bai

摘要:

我们引入了预交错代数的概念,它可以看作是一个交错代数,其乘积可以分解为两个以某种方式相容的部分。它也是树枝形双代数或预李代数的“替代”类似物。预交错代数的左、右乘法算子给出了相应交错代数的双模结构。对于预交错代数,存在一个(上边界)双代数理论,即预交错双代数,它具有著名的李双代数理论的所有熟悉的性质。特别地,预交错双代数等价于交错代数的相空间,我们的研究导致我们称之为预交错代数中的$PA$ -方程,它是经典Yang-Baxter方程的类似物。

英文摘要:

We introduce a notion of pre-alternative algebra which may be seen as an alternative algebra whose product can be decomposed into two pieces which are compatible in a certain way. It is also the "alternative" analogue of a dendriform dialgebra or a pre-Lie algebra. The left and right multiplication operators of a pre-alternative algebra give a bimodule structure of the associated alternative algebra. There exists a (coboundary) bialgebra theory for pre-alternative algebras, namely, pre-alternative bialgebras, which exhibits all the familiar properties of the famous Lie bialgebra theory. In particular, a pre-alternative bialgebra is equivalent to a phase space of an alternative algebra and our study leads to what we called $PA$-equations in a pre-alternative algebra, which are analogues of the classical Yang-Baxter equation.
