我们将根系统的推广定义为向量空间中具有某种对称性的一组向量。与通常根系的主要区别是各向同性根的存在。我们对不可约广义根系统进行分类。根据我们的分类,所有这些根系都是矛盾李超代数的根系,由 V.Kac 于 1977 年分类。
We define a generalization of a root system as a set of vectors in a vector space with some symmetry property. The main difference with the usual root systems is the existence of isotropic roots. We classify irreducible generalized root systems. As follows from our classification all such root systems are root systems of contragredient Lie superalgebras which were classified by V.Kac in 1977.
