Representation Theory of Finite Group Extensions

af Tullio Ceccherini-Silberstein

This monograph adopts an operational and functional analytic approach to the following problem: given a short exact sequence (group extension) 1 ¿ N ¿ G ¿ H ¿ 1 of finite groups, describe the irreducible representations of G by means of the structure of the group extension. This problem has attracted many mathematicians, including I. Schur, A.H. Clifford, and G. Mackey and, more recently, M. Isaacs, B. Huppert, Y.G. Berkovich & E.M. Zhmud, and J.M.G. Fell & R.S. Doran. The main topics are, on th... (Læs mere)
