The discrimination system for the polynomial method is applied to variant Boussinesq equations to classify single travelling wave solutions. In particular, we construct corresponding solutions to the concrete parameters to show that each solution in the classification can be realized.

In this paper, a generalised (3 + 1)-dimensional Kadomtsev–Petviashvili (KP) equation is considered. By transforming it into the bilinear form, one-, two- and multisoliton solutions are obtained. What is more, the Wronskian and Grammian solutions are also presented according to the Plücker relation and the Jacobi identity for determinants. In order to have an in-depth understanding of the dynamical properties of the equation, examples of each solution are given and some of them are plotted.
