Lump-type solutions, interaction solutions, and periodic lump solutions of the generalized (3+1)-dimensional Burgers equation

摘要

In this paper, the lump-type solutions, interaction solutions, and periodic lump solutions of the generalized (3 + 1)-dimensional Burgers equation were obtained by using the ansatz method. Based on a variable transformation, the generalized (3 + 1)-dimensional Burgers equation was transformed into a bilinear equation. And then, lump-type solutions, two kinds of interaction solutions, and periodic lump solutions were obtained via solutions of the bilinear equation. Fission and fusion phenomena are found in the process of interaction between lump-type soliton and one stripe soliton, which can derive the lumpoff wave solution. The dynamic characteristics of these solutions were vividly displayed by graphics.
