Bifurcation and travelling wave solutions for a (2+1)-dimensional <i>KdV</i> equation

Abstract

This work aims to study a new (2+1) KdV equation that is recently introduced in (Phys. Lett. A. 383: 728–731, 2019). By using the method of dynamical systems, we examine the bifurcation and construct exact travelling wave solutions for a (2+1) KdV equation. Exact parametric representations of all wave solutions are introduced and they are clarified graphically.
