Consistent Riccati expansion solvability and soliton-cnoidal wave interaction solution of a (2+1)-dimensional Korteweg-de Vries equation

In this paper, a (2+1)-dimensional KdV equation is investigated by using the consistent Riccati expansion (CRE) method proposed by Lou (2015). It is proved that the (2+1)-dimensional KdV equation is CRE solvable. Furthermore, soliton, cnoidal wave and soliton-cnoidal wave interaction solutions are obtained explicitly from different special solutions of the modified Schwarzian equation.
