INVERSE SCATTERING FOR THE DULLIN-GOTTWALD-HOLM EQUATION WITH A SOURCE
In this paper, the Cauchy problem for the Dullin–Gottwald–Holm equation with a source in the class of rapidly decreasing functions and a procedure is developed to construct the solution via the IST method is presented. In particular, from a physical perspective, it is analyzed that sources arise in...
