摘要
Four dimensional N = 2 generalized superconformal field theory can be defined by compactifying six dimensional A(N) (2, 0) theory on a Riemann surface with regular punctures. In previous studies, gauge coupling., constant space is identified with the moduli space of punctured Riemann surface M-g,M-n. We show that the weakly coupled gauge group description corresponds to a stable nodal curve, and the coupling space is actually the Deligne-Mumford compactification (M) over bar (g,n). We also give an algorithm to determine the weakly coupled gauge groups and matter contents in any duality frame.
