Discrete Gerdjikov-Ivanov models and their higher-order counterparts from the Cauchy matrix scheme
Xiao-gang Mu, Song-lin Zhao
The paper constructs fully discrete integrable versions of the Gerdjikov‑Ivanov equation and its higher‑order counterpart using the Cauchy matrix approach, and provides explicit so…

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…
