New exact solutions of Broer–Kaup–Kupershmidt equation

Abstract

Abstract:

CK method is a powerful direct method for nonlinear equation. By using the modified CK method , we obtain the Backlund transformation of the (2+1)-dimensional Broer–Kaup–Kupershmidt equations．So a lot of new solutions are found, and some known results in the paper [13-14] were generalized.

Key words: nonlinear equation, Broer–Kaup–Kupershmidt equation, exact solutions, CK method, Backlund transformation
