Character Expansions in Physics
arXiv:1011.3859 · doi:10.1063/1.3537848
Abstract
Expanding products of invariant functions of a group element as a series in the basis of characters of the irreducible representations of a group is widely used in many areas of physics and related fields. In this contribution a formula to generate such expansions and its various applications are briefly reviewed.
