Following Serre, a closed subgroup of a semisimple algebraic group G is called irreducible if it lies in no proper parabolic subgroup of G. In this paper we complete the classification of irreducible connected subgroups of exceptional algebraic groups, providing an explicit set of representatives for the conjugacy classes of such subgroups. Many consequences of this classification are also given. These include results concerning the representations of such subgroups on various G-modules: for example, the conjugacy classes of irreducible connected subgroups are determined by their composition factors on the adjoint module of G, with one exception. A result of Liebeck and Testerman shows that each irreducible connected subgroup X of G has only finitely many overgroups and hence the overgroups of X form a lattice. We provide tables that give representatives of each conjugacy class of connected overgroups within this lattice structure. We use this to prove results concerning the subgroup structure of G: for example, when the characteristic is 2, there exists a maximal connected subgroup of G containing a conjugate of every irreducible subgroup A1 of G"--Provided by publisher.Memoirs of the American Mathematical Society ;no. 1307.Linear algebraic groupsRepresentations of groupsEmbeddings (Mathematics)Maximal subgroupsGroup theory and generalizations -- Linear algebraic groups and related topics -- Representation theory for linear algebraic groupsmscGroup theory and generalizations -- Linear algebraic groups and related topics -- Linear algebraic groups over arbitrary fieldsmscGroup theory and generalizations -- Linear algebraic groups and related topics -- Exceptional groupsmscLinear algebraic groups.Representations of groups.Embeddings (Mathematics)Maximal subgroups.Group theory and generalizations -- Linear algebraic groups and related topics -- Representation theory for linear algebraic groups.Group theory and generalizations -- Linear algebraic groups and related topics -- Linear algebraic groups over arbitrary fields.Group theory and generalizations -- Linear algebraic groups and related topics -- Exceptional groups.512.220G0520G1520G41mscThomas Adam R1802232MiAaPQMiAaPQMiAaPQBOOK9910968798403321The Irreducible Subgroups of Exceptional Algebraic Groups4347805UNINA
