Abstract: (Elsevier)

Using the outer automorphisms of the affine algebra SU (n) , we show how the branching rules for the conformal subalgebra SU (pq) ⊃ SU (p) × SU (q) may be simply calculated. We demonstrate that new modular invariant combinations of SU (n) characters are obtainable from the branching rules.
