Abstract: Abstract This paper obtains soliton solutions of the Sasa–Satsuma model which governs the propagation of solitons through an optical fiber. Bright, dark, singular and combo-singular soliton solutions are recovered by the application of four integration… read more here.

Abstract: We formulate a $3\times3$ Riemann-Hilbert problem to solve the Cauchy problem for the Sasa-Satsuma equation on the line, which allows us to give a representation for the solution of Sasa-Satsuma equation. We then apply the… read more here.

DOI: 10.7566/jpsj.92.064003
Abstract: The Sasa-Satsuma equation, a higher-order nonlinear Schr\"{o}dinger equation, is an important integrable equation, which displays the propagation of femtosecond pulses in optical fibers. In this paper, we investigate a generalized Sasa-Satsuma(gSS) equation. The Darboux transformation(DT)… read more here.
