PhD Dissertation Project Summary:

In the early 1980’s, Kodama, Ablowitz and Satsuma, together with Santini, Ablowitz and Fokas, developed the formal inverse scattering theory of the Intermediate Long Wave (ILW) equation and explored its connections with the Benjamin-Ono (BO) and KdV equations. The ILW equation


models the behavior of long internal gravitational waves in stratified fluids of depth 0<δ<, where T is a singular operator which dependes on the depth δ. In the limit δ0, the ILW reduces to the Korteweg de Vries (KdV) equation, and in the limit δ, the ILW (at least formally) reduces to the Benjamin-Ono (BO) equation.

While the KdV equation is very well understood, a rigorous analysis of inverse scattering for the ILW equation remains to be accomplished. There is currently no rigorous proof that the inverse scattering procedure outlined by Kodama et al. solves the ILW, even for small data. My advisor, Peter Perry, our collaborator from the University of Oklahoma, Yilun "Allen" Wu, and I are working to ameliortate this situation.
