Abstract

General higher order breather and rogue wave (RW) solutions to the two-component long wave–short wave resonance interaction (2-LSRI) model are derived via the bilinear Kadomtsev–Petviashvili hierarchy reduction method and are given in terms of determinants. Under particular parametric conditions, the breather solutions can reduce to homoclinic orbits, or a mixture of breathers and homoclinic orbits. There are three families of RW solutions, which correspond to a simple root, two simple roots, and a double root of an algebraic equation related to the dimension reduction procedure. The first family of RW solutions consists of (Formula presented.) bounded fundamental RWs, the second family is composed of (Formula presented.) bounded fundamental RWs coexisting with another (Formula presented.) fundamental RWs of different a bounded state ((Formula presented.) being positive integers), while the third one has (Formula presented.) fundamental bounded RWs ((Formula presented.) being nonnegative integers). The second family can be regarded as the superpositions of the first family, while the third family can be the degenerate case of the first family under particular parameter choices. These diverse RW patterns are illustrated graphically.
