Special Bäcklund transformations and nonlinear superpositions for the non-integrable 4 field model. (English) Zbl 1092.81047
In this paper, the exact solution of the well-known \((N+1)\)-dimensional scalar field \(\phi^4\) model is studied by means of the special Bäcklund transformation and nonlinear superpositions. Some new type of exact solutions such as the conoid periodic-periodic interaction waves and the periodic solitary wave interaction solutions are explicitly given.
