具有表示的李代数上的Kupershirt-(对偶-)Nijenhuis结构

Kupershmidt-(dual-)Nijenhuis structures on a Lie algebra with a representation

Yuwang Hu, Jiefeng Liu, Yunhe Sheng

摘要:

本文首先研究了具有表示的李代数的无穷小变形,并引入了Nijenhuis对的概念,它给出了具有表示的李代数的平凡变形.然后,我们在具有表示的李代数上引入了Kupershirt-(对偶-)Nijenhuis结构的概念,它是Ravanpak,Rezaei-Aghdam和Haghighatdoost提出的$r$ - $n$结构($r$ -matrix-Nijenhuis结构)的推广.我们表明,一个Kupershirt-(双)Nijenhuis结构产生了一个层次的Kupershirt运营商。最后,我们定义了Rota-Baxter-Nijenhuis结构是李代数上关于伴随表示的Kupershmidt-Nijenhuis结构,并研究了Rota-Baxter-Nijenhuis结构与$r$ -matrix-Nijenhuis结构之间的关系.

英文摘要:

In this paper, first we study infinitesimal deformations of a Lie algebra with a representation and introduce the notion of a Nijenhuis pair, which gives a trivial deformation of a Lie algebra with a representation. Then we introduce the notion of a Kupershmidt-(dual-)Nijenhuis structure on a Lie algebra with a representation, which is a generalization of the $r$-$n$ structure ($r$-matrix-Nijenhuis structure) introduced by Ravanpak, Rezaei-Aghdam and Haghighatdoost. We show that a Kupershmidt-(dual-)Nijenhuis structure gives rise to a hierarchy of Kupershmidt operators. Finally, we define a Rota-Baxter-Nijenhuis structure to be a Kupershmidt-Nijenhuis structure on a Lie algebra with respect to the adjoint representation, and study the relation between Rota-Baxter-Nijenhuis structures and $r$-matrix-Nijenhuis structures.
