摘要：

We obtain the elliptic curve and the Seiberg-Witten differential for an N = 2 superconformal field theory which has an E(8) global symmetry at the strong coupling point tau = e(pi i/3). The differential has 120 poles corresponding to half the charged states in the fundamental representation of E(8), with the other half living on the other sheet. Using this theory, we flow down to E(7), E(6) and D-4. A new feature is a lambda(SW) for these theories based on their adjoint representations. We argue that these theories have different physics than those with lambda(SW) built from the fundamental representations. (C) 1997 Published by Elsevier Science B.V.
