New soliton-like solutions to the potential Kadomstev–Petviashvili (PKP) equation

摘要

In this paper, new soliton-like solutions are obtained for (2+1)-dimensional potential Kadomstev–Petviashvili (PKP) equation by using the symbolic computation method developed by Gao and Tian. Solitary wave solutions obtained in [Appl. Math. Comput 123 (2001) 29] are merely a special case in this paper. The method can also be extended to other types of nolionear evolution equations in mathematical physics.
