限制Cartan型李代数的群分次

Group gradings on restricted Cartan type Lie algebras

Yuri Bahturin, Mikhail Kochetov

摘要:

对给定的阿贝尔群G,利用数值和群论不变量对W(m;1)和S(m;1)(m ≥ 2)型单限制李代数上G-分次的同构类进行了分类.我们的主要工具是自同构群方案,我们确定的简单限制李代数类型S(m;1)和H(m;1)。假设基域是特征p>3的代数闭场。

英文摘要:

For a given abelian group G, we classify the isomorphism classes of G-gradings on the simple restricted Lie algebras of types W(m;1) and S(m;1) (m>=2), in terms of numerical and group-theoretical invariants. Our main tool is automorphism group schemes, which we determine for the simple restricted Lie algebras of types S(m;1) and H(m;1). The ground field is assumed to be algebraically closed of characteristic p>3.
