A type of bounded traveling wave solutions for the Fornberg–Whitham equation

In this paper, by using bifurcation method, we successfully find the Fornberg–Whitham equation ut − uxxt + ux = uuxxx − uux +3uxuxx, has a type of traveling wave solutions called kink-like wave solutions and antikinklike wave solutions. They are defined on some semifinal bounded domains and possess properties of kink waves and anti-kink waves. Their implicit expressions are obtained. For some concrete data, the graphs of the implicit functions are displayed, and the numerical simulation is made. The results show that our theoretical analysis agrees with the numerical simulation.
