REDUCTION THEOREMS FOR TRIPLES OF SHORT ROOT SUBGROUPS IN CHEVALLEY GROUPS

摘要

Reduction theorems for triples of short root unipotent subgroups in Chevalley groups of type B_l and C_l are proved. The main result asserts that except for one case, any subgroup generated by such a triple is conjugate to a subgroup of G(B_4, K)U K) or K)U(C_5, K), respectively. Bibliography: 36 titles.
