Airy and Painlevé asymptotics for the mKdV equation
Christophe Charlier, Jonatan Lenells
We consider the higher order asymptotics for the mKdV equation in the Painlevé sector. We first show that the solution admits a uniform expansion to all orders in powers of $t^{-1/…

On the spectral problem associated with the time-periodic nonlinear Schrödinger equation
Jonatan Lenells, Ronald Quirchmayr
According to its Lax pair formulation, the nonlinear Schrödinger (NLS) equation can be expressed as the compatibility condition of two linear ordinary differential equations with a…
