Aschbacher: Subgroup structure of finite simple groups

My talks will be about subgroup lattices of finite groups, particularly subgroups of groups of Lie type, and most particularly about subgrps of classical grps.
Sections 13, 30, 43, and 47, plus Chapter 7 of my book Finite Group Theory would provide an introduction to the classical groups and the groups of Lie type.
