A Lie algebra L is said to be -graded if it contains a simple subalgebra isomorphic to such that the -module L decomposes into copies of the adjoint module, the trivial module, the natural module V, its symmetric and exterior squares and and their duals. We describe the multiplicative structures and the coordinate algebras of -graded Lie algebras for , classify these Lie algebras and determine their central extensions.

由权重系统分级李代数(Θ Ñ,SL Ñ)
一个李代数L据说是-分级,如果它包含一个简单的子代数 同构 这样 模块L分解为伴随模块,平凡模块,自然模块V,其对称平方和外部平方的副本 和 和他们的对偶。我们描述了乘法结构和坐标代数的李代数 ,对这些李代数进行分类并确定其中心扩展。
