Cauchy matrix approach to novel extended semi-discrete KP-type systems
Hong-juan Tian, Abdselam Silem
Two novel extended semi-discrete KP-type systems, namely partial differential-difference systems with one continuous and two discrete variables, are investigated. Introducing an ar…

Discrete rogue waves and blow-up from solitons of a nonisospectral semi-discrete nonlinear Schrödinger equation
Abdselam Silem, Hua Wu, Da-jun Zhang
We investigate the nonisospectral effects of a semi-discrete nonlinear Schrödinger equation, which is a direct integrable discretisation of its continuous counterpart. Bilinear for…
