Abstract:Let be a restricted Lie algebra over an algebraically closed field of characteristic . Motivated by the behavior of geometric invariants of the so-called -modules of constant -rank ( ), we study the projective variety of two-dimensional elementary abelian subalgebras. If , then the topological space , associated to the factor algebra of by its center , is shown to be connected. We give applications concerning categories of -modules of constant -rank and certain invariants, called -degrees.

基本的阿贝尔李代数的种类和模的阶数
摘要:设特征为的代数封闭域上的受限李代数。受所谓的常数-rank(- )的-模的几何不变性的影响,我们研究了二维基本阿贝尔亚代数的射影变体。如果为,则表示与其中心的因子代数关联的拓扑空间是连通的。我们给出有关常量-rank和某些不变式-modules的-modules类的应用程序。
