Darboux transformation and soliton solutions of the (2+1)-dimensional Schwarz–Korteweg–de Vries equation

Abstract

In this paper, we deduce the (2+1)-dimensional Schwarz–Korteweg–de Vries equation from two (1+1)-dimensional equations. Based on the resulting Lax pairs, we present its [Formula: see text]-fold Darboux transformation. From a trivial solution, we get [Formula: see text]-soliton and [Formula: see text]-soliton solutions of the (2+1)-dimensional Schwarz–Korteweg–de Vries equation. The asymptotic analyses of the [Formula: see text]-soliton, [Formula: see text]-soliton and [Formula: see text]-soliton solutions are presented theoretically and graphically.
