Abstract
In this paper, we investigate the classical Drinfel’d–Sokolov–Wilson equation (DSWE) u t + pvv t = 0 , v t + ruv x + su x v + qv xxx = 0 , where p, q, r, s are some nonzero parameters. Some explicit expressions of solutions for the equation are obtained by using the bifurcation method and qualitative theory of dynamical systems. These solutions contain solitary wave solutions, blow-up solutions, periodic solutions, periodic blow-up solutions and kink-shaped solutions. Some previous results are extended.
