Abstract

A variety of new types of nonautonomous combined multi-wave solutions of the (\(2+1\))-dimensional variable coefficients KdV equation is derived by means of the generalized unified method. These solutions are classified into three categories, namely multi- soliton, periodic and elliptic solutions. The physical insight of the waves is dressed for different values of the free parameters in the obtained solutions.
