Riemann-Hilbert approach for the nonlocal modified Korteweg-de Vries equation with a step-like oscillating background
Yan Rybalko
The paper develops a Riemann‑Hilbert framework for solving the Cauchy problem of the nonlocal modified Korteweg‑de Vries equation with oscillating step‑like boundary conditions and…

The integrable nonlocal nonlinear Schrödinger equation with oscillatory boundary conditions: long-time asymptotics
Yan Rybalko, Dmitry Shepelsky, Shou-Fu Tian
We consider the Cauchy problem for the integrable nonlocal nonlinear Schrödinger equation \[ \I q_{t}(x,t)+q_{xx}(x,t)+2 q^{2}(x,t)\bar{q}(-x,t)=0, \] subject to the step-like ini…
