This paper investigates a generalized discrete Hirota equation and constructs the Nth-fold Darboux transformation based on Lax pair. It obtains and analyzes the solutions for one- and two-breathers. The first- and second-order rogue wave solutions are derived and investigated, including discussion on the influences of parameters. Additionally, the interaction solutions between rogue wave and one breather are constructed and studied.
Under investigation in this paper is a generalized discrete Hirota equation. Based on Lax pair, the Nth-fold Darboux transformation is constructed. The one- and two-breather solutions are obtained and analyzed. The first- and second-order rogue wave solutions are derived and investigated. The influences of parameters for solutions are discussed. In particular, the different structures of second-order rogue wave are observed. Moreover, the interaction solutions between rogue wave and one breather are constructed and studied.
