Stability of the Periodic Toda Lattice: Higher Order Asymptotics
Spyridon Kamvissis, Gerald Teschl
In a recent paper we have considered the long time asymptotics of the periodic Toda lattice under a short range perturbation and we have proved that the perturbed lattice asymptoti…

Stability of Periodic Soliton Equations under Short Range Perturbations
Spyridon Kamvissis, Gerald Teschl
We consider the stability of (quasi-)periodic solutions of soliton equations under short range perturbations and give a complete description of the long time asymptotics in this si…

Asymptotics via Steepest Descent for an Operator Riemann-Hilbert Problem
Spyridon Kamvissis
In this paper, we take the first step towards an extension of the nonlinear steepest descent method of Deift, Its and Zhou to the case of operator Riemann-Hilbert problems. In part…
