• on conjugacy classes. We have seen already that irreducible characters form a basis of the space of class functions. We are now going to prove that it is in fact an orthonormal basis. If χi is a character of S1, then. < χi, χj >= δij. (notice in particular that this imples that irreducible characters are distinct).

  • The representation theory of finite groups has two ingredients, conjugacy classes and irreducible representations, and a character table, which is a nonsingular matrix making them ``dual'' (I apologise to group theorists for this gratuitous vulgarity).
    • This method is known as the Fischer-Clifford Theory and uses Fischer-Clifford matrices, as one of the tools, to compute character tables. This is derived from the Clifford theory. Here G is an extension of a group N by a finite group G, that is G = N.G. We then construct a non-singular matrix for each conjugacy class of G/N =G.
