四维实李代数上的复结构和biHermitian结构

Complex and biHermitian structures on four dimensional real Lie algebras

A. Rezaei-Aghdam, M. Sephid

摘要:

给出了计算低维实李代数上复结构和双厄米结构的一种新方法。该方法首先利用非坐标基将李群上的Nijenhuis张量场和双厄米特结构关系变换为李群上的张量关系。然后,我们使用伴随表示写这些关系的矩阵形式;在这种方式下,通过解决这些矩阵关系,并使用四维实李代数的自同构群,我们得到并分类所有复杂的和biHermitian结构的四维实李代数。

英文摘要:

We give a new method for calculation of complex and biHermitian structures on low dimensional real Lie algebras. In this method, using non-coordinate basis, we first transform the Nijenhuis tensor field and biHermitian structure relations on Lie groups to the tensor relations on their Lie algebras. Then we use adjoint representation for writing these relations in the matrix form; in this manner by solving these matrix relations and using automorphism groups of four dimensional real Lie algebras we obtain and classify all complex and biHermitian structures on four dimensional real Lie algebras.
