An Introduction to Harmonic Analysis on Semisimple Lie by V. S. Varadarajan

By V. S. Varadarajan

Now in paperback, this graduate-level textbook is a superb advent to the illustration concept of semi-simple Lie teams. Professor Varadarajan emphasizes the improvement of imperative issues within the context of distinct examples. He starts with an account of compact teams and discusses the Harish-Chandra modules of SL(2,R) and SL(2,C). next chapters introduce the Plancherel formulation and Schwartz areas, and convey how those bring about the Harish-Chandra thought of Eisenstein integrals. the ultimate sections reflect on the irreducible characters of semi-simple Lie teams, and comprise specific calculations of SL(2,R). The ebook concludes with appendices sketching a few uncomplicated themes and with a accomplished consultant to additional examining. This really good quantity is very compatible for college kids in algebra and research, and for mathematicians requiring a readable account of the subject.
