Twenty papers present and review recent results in symmetric spaces, the product formula for the Harish-Chandra c -function, and the theory of representation and other aspects of Lie groups. Two of the papers survey Karpelevich's (1927-2000) work on the boundaries of symmetric spaces and subalgebras of real semisimple Lie algebras. Other topics include the heat kernel on non-compact symmetric spaces, quantization of Alekseev-Meinrenken dynamical r -matrices, the dual horospherical Radon transform as a limit of spherical Radon transforms, a multiplicity one theorem in the orbit method, and a formal identity for affine root systems. The series was formerly titled "Advances in Soviet mathematics." Annotation (c) Book News, Inc., Portland, OR (booknews.com)
