广义仿射根超系

Extended Affine Root Supersystems

Malihe Yousofzadeh

摘要:

具有关于非零toral子代数的权空间分解的李代数$\LL,$与其相应的根系的相互作用形成了研究$\LL.$的结构的有力工具。这特别表明,除了与李代数的联系之外,还可以系统地研究根系。虽然在李代数水平上已经有了很多研究,但在李超代数水平上还没有考虑这种方法。本文引入并研究了广义仿射根超系,它是仿射反射系统和局部有限根超系的推广。广义仿射根超系是广义仿射李代数和包括仿射李超代数在内的不变仿射反射代数的超形式的根系。本文的工作为研究这类李超代数的结构提供了一个框架,称之为扩展仿射李超代数。

英文摘要:

The interaction of a Lie algebra $\LL,$ having a weight space decomposition with respect to a nonzero toral subalgebra, with its corresponding root system forms a powerful tool in the study of the structure of $\LL.$ This, in particular, suggests a systematic study of the root system apart from its connection with the Lie algebra. Although there have been a lot of researches in this regard on Lie algebra level, such an approach has not been considered on Lie superalgebra level. In this work, we introduce and study extended affine root supersystems which are a generalization of both affine reflection systems and locally finite root supersystems. Extended affine root supersystems appear as the root systems of the super version of extended affine Lie algebras and invariant affine reflection algebras including affine Lie superalgebras. This work provides a framework to study the structure of this kind of Lie superalgebras refereed to as extended affine Lie superalgebras.
