$SU(2)\times SU(2)$上的对偶左不变殆复结构

Dual left-invariant almost complex structures on the $SU(2)\times SU(2)$

N. A. Daurtseva

摘要:

对于每个左不变的几乎厄米特结构$(g,I)$,存在非退化的3-形式$dω_I$,$ω_I(X,Y)=g(IX,Y)$,其中$g$是$M=S^3\times S^3=SU(2)\times SU(2)$上的Killing-Cartan度量.已知的\cite{H1},即6维流形上的任意非退化3-形式,具有一些附加性质,定义了几乎复结构。给出了由$dω_I$定义几乎复结构$J_I$的条件。研究了$J_I$的性能。

英文摘要:

There exist non-degenerate 3-form $dω_I$, $ω_I(X,Y)=g(IX,Y)$, for each leftinvariant almost Hermitian structure $(g,I)$, where $g$ is Killing-Cartan metric on the $M=S^3\times S^3=SU(2)\times SU(2)$. Known \cite{H1}, that arbitrary non-degenerate 3-form on the 6-dimensional manifold, with some additional properties defines the almost complex structure. Condition for $I$ to define almost complex structure $J_I$ by $dω_I$ is obtained. Properties of $J_I$ are researched.
