Representations of Compact Groups,In this chapter, we shall extend to compact topological groups many of the properties proved in the case of finite groups. Some properties will be stated without proof.

Lie Groups SU(2) and SO(3),We know that . and . are real Lie algebras of dimension 3. We shall show that they are isomorphic by showing that there are bases of each in which the commutation relations are the same.

Spherical Harmonics,the rotation group SO(3). Each irreducible representation of SO(3) can be realized in a finite-dimensional Hilbert space of functions on the sphere, the restrictions of harmonic homogeneous polynomials of a given degree, and this representation is unitary. We shall determine an orthonormal basis of
