Jordan超代数的结构与TKK代数

On structure and TKK algebras for Jordan superalgebras

Sigiswald Barbier, Kevin Coulembier

摘要:

我们比较了一些不同的定义结构代数和TKK结构的约旦(超)代数出现在文献中。我们证明了,对于有单位元的超代数,所有的结构代数和TKK结构的定义分为两种情况。此外,一个可以作为另一个的超导子的李超代数得到。我们还表明,对于非酉超代数,更多的定义变得不等价。作为应用,我们得到了特征为零的代数闭域上的有限维单Jordan超代数的相应李超代数。

英文摘要:

We compare a number of different definitions of structure algebras and TKK constructions for Jordan (super)algebras appearing in the literature. We demonstrate that, for unital superalgebras, all the definitions of the structure algebra and the TKK constructions fall apart into two cases. Moreover, one can be obtained as the Lie superalgebra of superderivations of the other. We also show that, for non-unital superalgebras, more definitions become non-equivalent. As an application, we obtain the corresponding Lie superalgebras for all simple finite dimensional Jordan superalgebras over an algebraically closed field of characteristic zero.
