Standing lattice solitons in the discrete NLS equation with saturation

G. L. Alfimov, A. S. Korobeinikov, C. J. Lustri +1

We consider standing lattice solitons for discrete nonlinear Schrodinger equation with saturation (NLSS), where so-called transparent points were recently discovered. These transpa…

Generalized Solitary Waves in a Finite-Difference Korteweg-de Vries Equation

Nalini Joshi, Christopher J. Lustri

Generalized solitary waves with exponentially small non-decaying far field oscillations have been studied in a range of singularly-perturbed differential equations, including highe…

Nonlinear $q$ -Stokes phenomena for $q$ -Painlevé I

Nalini Joshi, Christopher Lustri, Steven Luu

We consider the asymptotic behaviour of solutions of the first $q$ -difference Painlevé equation in the limits $∣ q ∣ \to 1$ and $n \to \infty$ . Using asymptotic power se…
