Major advances have been made in the area of Algebraic Groups and Homogeneous Spaces in recent decades. This volume contains articles by several leading experts in central topics in the area, including representation theory in characteristic p, combinatorial representation theory, flag varieties, Schubert varieties, vector bundles, loop groups and Kac-Moody Lie algebras, Galois cohomology of algebraic groups, and Tannakian categories. In addition to original papers in these areas, the volume includes a survey on representation theory in characteristic p by H. Andersen and an article by T.A. Springer on Armand Borel's work in algebraic groups and Lie groups.
