With the classification of the finite simple groups complete, much work has gone into the study of maximal subgroups of almost simple groups. In this volume the authors investigate the maximal subgroups of the finite classical groups and present research into these groups as well as proving many new results. In particular, the authors develop a unified treatment of the theory of the 'geometric subgroups' of the classical groups, introduced by Aschbacher, and they answer the questions of maximality and conjugacy and obtain the precise shapes of these groups. Both authors are experts in the field and the book will be of considerable value not only to group theorists, but also to combinatorialists and geometers interested in these techniques and results. Graduate students will find it a very readable introduction to the topic and it will bring them to the very forefront of research in group theory.
This monograph studies generating sets of almost simple classical groups, by bounding the spread of these groups.
Then one of the following holds: (2) (1) M is a parabolic subgroup, M is the normalizer of some connected reductive ... An elementary abelian r-subgroup R of G, with r = char(k), is called a Jordan subgroup of G if it satisfies the ...
This is the first time that all the finite simple groups have been treated together in this way and the book points out their connections, for example between exceptional behaviour of generic groups and the existence of sporadic groups, and ...
Let x = ˆxZ∈ T be an element of order p, and assume that x has fixed points on Ω. Then ˆx ∈ GLm(q)× GL n−m(q) =: L is L-conjugate to[Japp,...,Ja11 ,Jbpp ,...,Jb11], where ∑v vav =m and ∑v vbv =n−m, so ˆx is GLn(q)-conjugate to ...

This book concerns the theory of unipotent elements in simple algebraic groups over algebraically closed or finite fields, and nilpotent elements in the corresponding simple Lie algebras.
A classical theorem of Jordan states that every finite transitive permutation group contains a derangement.
The methods use computers in small cases and are purely theoretical for the infinite series using root systems or orders with involutions.
