摘要
In this paper, the direct method is adopted to integrate the coupled nonlinear Klein–Gordon equations with power law nonlinearity. The exact single topological and non-topological soliton solutions of the one-coupled, two-coupled and N-coupled nonlinear Klein–Gordon equations with power law nonlinearity are proposed explicitly. Among these soliton solutions there are some constraint conditions which guarantee the existence of the solutions.
