摘要: Under investigation is a generalized (3 + 1)-dimensional variable- coefficient Kadomtsev– Petviashvili equation in fluid mechanics. Various exact analytical solutions are obtained by Hirota’s bilinear method, such as lump-type, breather wave and kink-solitary solutions. We discuss the interaction between lump solitary waves, periodic wave. The physical structure propagation characteristics of shown some 3D graphics.
