Lump, lump-trigonometric, breather waves, periodic wave and multi-waves solutions for a Konopelchenko–Dubrovsky equation arising in fluid dynamics.

In this paper, we get certain the lump-trigonometric solutions and rogue waves with predictability of a (2+1)-dimensional Konopelchenko–Dubrovsky equation in fluid dynamics with the assistance of Maple based on the Hirota bilinear form. We first construct a general quadratic form to get the general lump solution for the referred model. At the same time the lump-trigonometric solutions are concluded with plenty of solutions, in which the lump solution localized in all directions in space. The analytical solutions obtained are employed in the investigation of the impacts of the parameters on type of solutions. Moreover, when the lump solution is cut by twin-solitons, the special rogue waves are also introduced. Furthermore, we obtain a new sufficient solutions containing breather wave, cross-kink, periodic-kink, multi-waves and solitary wave solutions. The developed models in this work will serve as the basis for comparisons for the analytical solutions of the subsequent works on the performance of mentioned equation. It is worth noting that the emerging time and place of the rogue waves depend on the moving path of lump solution. [ABSTRACT FROM AUTHOR]
