Abstract
We present lump-type solutions and interaction solutions to an extended (3 + 1)-dimensional Jimbo-Miwa-like equation. Three classes of lump-type solutions are obtained by the Hirota bilinear method. Interaction solutions are among lump-type solutions, two kink waves and periodic waves, and between two kink waves and a periodic wave are computed. Dynamical characters of the obtained solutions are graphically exhibited. These wave solutions enrich the dynamical theory of higher-dimensional non-linear dispersive wave equations.
