Nambu结构与相伴的双代数胚

Nambu Structures And Associated Bialgebroids

Samik Basu, Somnath Basu, Apurba Das, Goutam Mukherjee

摘要:

本文研究了李代数胚和双代数胚已知结果的高阶推广。证明了$n$ -李代数体结构对应于Gerstenhaber代数的$n$ -元推广,并隐含于对偶丛上线性Poisson结构的$n$ -元推广.一个Nambu-Poisson流形($n>2$阶)产生一个特殊的双代数胚结构,称为弱Lie-Filippov双代数胚($n$阶)。进一步证明了这种双代数胚在基流形上正则地诱导出Nambu-Poisson结构。最后,Nambu李群的切空间给出了点上弱Lie-Filippov双代数胚的一个例子。

英文摘要:

This paper investigates higher order generalizations of well known results for Lie algebroids and bialgebroids. It is proved that $n$-Lie algebroid structures correspond to $n$-ary generalization of Gerstenhaber algebras and are implied by $n$-ary generalization of linear Poisson structures on the dual bundle. A Nambu-Poisson manifold (of order $n>2$) gives rise to a special bialgebroid structure which is referred to as a weak Lie-Filippov bialgebroid (of order $n$). It is further demonstrated that such bialgebroids canonically induce a Nambu-Poisson structure on the base manifold. Finally, the tangent space of a Nambu Lie group gives an example of a weak Lie-Filippov bialgebroid over a point.
