摘要
以L表示复数域上单李代数,其根系Φ中所有根等长(A型、D型或E型李代数),L1为L特定的子代数;以L(F)表示任意域F上L型Chevaley群,则L1(F)<L(F).本文正是要定出L1(F)H在L(F)中的所有扩群,并获得L(F)的一类新的极大子群.
Let L be a simple Lie algebra over an arbitrary field F, L1 a paticular subalgebra of L, L(F) a chevalley group of type L. Obviously, L1(F)H<L(F). We wish to determine all the overgroups of L1(F)H in L(F) when L is of typs Al(l≥2), Dl(l≥6), E6, E7, E8. At last we obtain one type of maximal subgroup of L(F).
