                | In this paper, we investigate a generalized (3+1)-dimensional variable-coefficient B-type Kadomtsev-Petviashvili equation in fluid dynamics. Based on bilinear forms, the solutions to dimensionally reduced generalized variable coefficient B-type Kadomtsev-Petviashvili equation in (3+1)-dimensions are computed through symbolic computation. The property of solutions is investigated and exhibited vividly by three dimensional plots and contour plots. |
