Lump solutions to the Kadomtsev-Petviashvili I equation with a self-consistent source

Based on symbolic computations, lump solutions to the Kadomtsev-Petviashvili I (KPI) equation with a self-consistent source (KPIESCS) are constructed by using the Hirota bilinear method and an ansatz technique. In contrast with lower-order lump solutions of the Kadomtsev-Petviashvili (KP) equation, the presented lump solutions to the KPIESCS exhibit more diverse nonlinear phenomena. The method used here is more natural and simpler.
