| Abstract: | This paper studies the topological as well as the non-topological solitons due to the nonlinear Klein-Gordon equations, in presence of perturbation terms. There are five forms of nonlinearity that will be considered. The He's semi-inverse variational principle will be used to carry out the integration. |
