Abstract
This paper investigates a multi-component plasmas model described by the (3 ＋ 1)-dimensional extend Kadomtsev–Petviashvili equation (eKPe). Lump and soliton solutions are obtained via the Hirota’s bilinear form. Collisions between lump solutions and one solitary wave are studied. Furthermore, collisions between lump solutions and two solitary waves are discussed. The dynamical behaviors of the derived solutions are shown via 3D- and contour plots.
