Spatially discrete Hirota equation: rational and breather solution, gauge equivalence, and continuous limit. (English) Zbl 1509.35283

Summary: It is well known that the nonlinear Schrödinger equation, the Hirota equation, and their integrable discrete versions are very important integrable equations. These integrable equations not only have deep integrability theory, but also have wide physical applications. In this paper, we focus on an integrable spatially discrete Hirota equation. The new Lax pair, Darboux transformation, rational wave solution, rogue wave solution, breather solutions and gauge equivalent structure of the spatially discrete Hirota equation are investigated. The continuous limit of the rogue wave solution and breather solution of the discrete Hirota equation yields the counterparts of the Hirota equation, which shows that the spatially discrete Hirota equation is a very good model for the numerical analysis for considering the Cauchy problem with a general initial date of the Hirota equation. Besides, we prove that this spatially discrete Hirota equation is gauge equivalent to a discrete integrable generalized Heisenberg spin model under the discrete gauge transformation. In this performance, we see that utilizing the new Lax pair, an essential properties of integrability, of the spatially discrete Hirota equation plays a significant role in the investigation of continuous limit of Lax pair of discrete integrable generalized Heisenberg spin model.
