Lump type solutions: Backlund transformation and spectral properties

Analysis of PDEs 2023-12-05 v1

Abstract

There are various different ways to obtain traveling waves of lump type for the KP equation. We propose a general and simple approach to derive them via a Backlund transformation. This enables us to establish an explicit connection between those low energy solutions and high energy ones. Based on this construction, spectral analysis of the degree 66 solutions is then carried out in details. The analysis of higher energy ones can be done in an inductive way.
