Topological and non-topological solitons of nonlinear KleinGordon equations by He's semi-inverse variational principle
This paper studies the topological as well as the non-topological solitons due to the nonlinear KleinGordon 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.
