摘要：

We investigate domain wall junctions in a generalized Wess-Zumino model with a Z(N) symmetry. We present a method to identify the junctions that are potentially BPS saturated. We then use a numerical simulation to show that those junctions indeed saturate the BPS bound for N = 4. In addition, we study the decay of unstable non-BPS junctions.
