SL(2,7) and PSL(2,7) subgroups of E(,8)(C) and their actions on a maximal torus.

摘要

This dissertation classifies subgroups L of the complex Lie group G of type ;Chapter 3 classifies subgroups L which centralize an involution z of trace ;Chapter 4 considers groups L which normalize a maximal torus T of G, and studies the action of L on the
