Completeness of the 3j-Symbols for the Group SL(2, ℂ)
Abstract
The basic formulas for the unitary principal series representations of the group SL(2, ℂ) are given, and the decomposition of a tensor product of two representations into irreducible representations is considered. A simple proof of the completeness of the 3j-symbols is given.
