Download or read book Irreducible Subgroups of Exceptional Algebraic Groups written by Donna M. Testerman and published by American Mathematical Soc.. This book was released on 1988 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Let [italic]Y be a simply-connected, simple algebraic group of exceptional type, defined over an algebraically closed field [italic]k of prime characteristic [italic]p > 0. The main result describes all semisimple, closed connected subgroups of [italic]Y which act irreducibly on some rational [italic]k[italic]Y module [italic]V. This extends work of Dynkin who obtained a similar classification for algebraically closed fields of characteristic 0. The main result has been combined with work of G. Seitz to obtain a classification of the maximal closed connected subgroups of the classical algebraic groups defined over [italic]k.
