- Received Date: 1992-08-27
Abstract: Branching rules for group chain N(U)⊃SP(N)⊃O(3) of the irreducible representations[2a1b] of U(N) are discussed by formulas of group direct product decomposition. Simple recurrence formulas of these branching rules are obtained. It provides a simple method to find the branching rules for this type of problem. They are very efficient to simplify the calculations of Fractional Parentage Coefficients. This method can also be used in finding branching rules for group chain U(N)⊃O(N)⊃0(3).
