Small Solitons and Multi-Solitons in Generalized Davey-Stewartson System

preprint2022arXivOpen access

Abstract

This paper is concerned with the generalized Davey-Stewarston system in two dimensional space. Existence and stability of small solitons are proved by solving two correlative constrained variational problems and spectrum analysis. In addition, multi-solitons with different speeds are constructed by bootstrap argument.
