非交换几何中向量场的李括号

Lie bracket of vector fields in noncommutative geometry

Pascual Jara, David Llena

摘要:

本文的目的是为了避免在非对易条件下定义向量场时遇到的与李括号有关的困难,因为它们是由Woronowicz,Schmudgen-Schleman和Aubieri-Schupp定义的.我们通过由Borowiec引入的Cartan对,扩展了向量场的定义,把它们看作是代数的导子。然后,利用平移,我们引入不变向量场。最后,将Dubois-Violette实现的李括号的定义,考虑代数中心的元素,也推广到这些不变的向量场。

英文摘要:

The aim of this paper is to avoid some difficulties, related with the Lie bracket, in the definition of vector fields in a non commutative setting, as they were defined by Woronowicz, Schmudgen--Schuler and Aschieri--Schupp. We extend the definition of vector fields to consider them as derivations of the algebra, through Cartan pairs introduced by Borowiec. Then, using translations, we introduce the invariant vector fields. Finally, the definition of Lie bracket realized by Dubois--Violette, considering elements in the center of the algebra, is also extended to these invariant vector fields.
