Lie Theory

* First of three independent, self-contained volumes under the general title, "Lie Theory," featuring original results and survey work from renowned mathematicians.* Contains J. C. Jantzen's "Nilpotent Orbits in Representation Theory," and K.-H. Neeb's "Infinite Dimensional Groups and their Representations."* Comprehensive treatments of the relevant geometry of orbits in Lie algebras, or their duals, and the correspondence to representations.* Should benefit graduate students and researchers in mathematics and mathematical physics.
