Abstract: | We show that the E6 and E8 modular invariant combinations of A(1)1 characters in the classification of Cappelli, Itzykson and Zuber can be realized as partition functions of k=1 conformally invariant WZW models on the group manifolds of Sp(4) and G2, respectively. Together with the D4 combination, which is known to be realized by the WZW model on SU(3), these are the only such cases where the SU(2) local symmetry extends to a larger one. The E7 combination is briefly discussed. |
