Lump Solutions to a Jimbo-Miwa Like Equations (1611.04478v1)

Abstract: A Jimbo-Miwa like nonlinear differential equation in (3+1)-dimensions is developed through a generalized bilinear equation with the generalized bilinear derivatives. Based on the generalized bilinear forms, two classes of lump solutions, rationally localized in all directions in the space, and a class of complex lump type solution are generated from a Maple search of quadratic polynomial function solution to the proposed Jimbo-Miwa like equation. The apposite conditions to assurance analyticity and rational localization of the solutions are offered. Each of the resulting lump solutions hold six free parameters, two of which are due to the translation invariance of the Jimbo-Miwa like equations and four of which only require to satisfy the presented apposite conditions of being lump solutions. We also generate circle or ellipse shape solutions from the obtained solutions using different conditions on the lumps solutions. Moreover, figures are given to visualize the properties of the explicit solutions.
