报告简介： This talk will introduce the nonautonomous lump solutions and mixed lump–stripe soliton solutions of a variable–coefficient Kadomtsev–Petviashvili equation. The displacements, trajectories and velocities of the nonautonomous lump wave are investigated by taking the variable–coefficient as the simplest power function, exponential function and sine function, respectively. In addition, the mixed lump–stripe soliton solutions are found to have periodic fission and fusion phenomena.
