Riemann-Hilbert problems for a nonlocal reverse-spacetime Sasa-Satsuma hierarchy of a fifth-order equation and its soliton solutions

Ahmed M. G. Ahmed, Alle Adjiri, Solomon Manukure

We aim to present and analyze a nonlinear nonlocal reverse-spacetime fifth-order scalar Sasa-Satsuma equation, based on a nonlocal $5\times 5$ matrix AKNS spectral problem. Starti…
