Discrete Gerdjikov-Ivanov models and their higher-order counterparts from the Cauchy matrix scheme
Xiao-gang Mu, Song-lin Zhao
The Gerdjikov-Ivanov (GI) equation is an important model in the derivative nonlinear Schrodinger system, yet its fully discrete integrable analogues remain unexplored. In this pape…

Discretization of the Mikhailov model
Song-lin Zhao, Xiao-gang Mu, Da-jun Zhang
In this paper the Mikhailov model is discretized by means of the Cauchy matrix approach. A pair of discrete Miura transformations are constructed. The discrete Mikhailov model is a…
