Notes on Lie Algebras - Cornell University
pi.math.cornell.eduThe first chapter contains the necessary general facts about Lie algebras. Semisimplicity is defined and Cartan’s criterion for it in terms of a certain quadratic form, the Killing form, is developed. The chapter also brings the representations of sl(2,C), the Lie algebra consisting of the 2 ×2 complex

math.berkeley.eduseveral important C*-algebras such as C(G) from it related to the representation theory of G. If Ais a C*-algebra and Ga locally compact group acting on A, then we can de ne a crossed product C*-algebra Ao G. There is an analogous construction 1. for foliated manifolds. Another quite di erent example is the CAR-algebra.
