摘要

In this paper we use integral method and numerical approach to show that Degasperis-Procesi equation u(1) - u(xx1) + 4uu(x) = 3u(x)u(xx) + uu(xxx), has new bounded waves which are defined on some semifinal bounded domains and possess properties of kink waves or antikink waves. Their implicit expressions are obtained. For a set of concrete data, the planar diagrams of the implicit expressions and their numerical simulations are displayed. It is seen that the planar diagrams are identical with the simulations.
