Benjamin in 1969. The text of the first edition has been corrected and revised. Accordingly, this book presents foundational material on algebraic groups, Lie algebras, transformation spaces, and quotient spaces. After establishing these basic topics, the text then turns to solvable groups, general properties of linear algebraic groups and Chevally's structure theory of reductive groups over algebraically closed groundfields. The remainder of the book is devoted to rationality questions over non-algebraically closed fields. This second edition has been expanded to include material on central isogenies and the structure of the group of rational points of an isotropic reductive group. The main prerequisite is some familiarity with algebraic geometry. The main notions and results needed are summarized in a chapter with references and brief proofs.Graduate Texts in Mathematics,0072-5285 ;126Topological groupsLie groupsTopological Groups, Lie Groupshttps://scigraph.springernature.com/ontologies/product-market-codes/M11132Topological groups.Lie groups.Topological Groups, Lie Groups.512.55512.482Borel Armandauthttp://id.loc.gov/vocabulary/relators/aut45077BOOK9910789343503321Linear algebraic groups79356UNINA
