Freezing of energy of a soliton in an external potential

Dario Bambusi, Alberto Maspero

In this paper we study the dynamics of a soliton in the generalized NLS with a small external potential $ε V$ of Schwartz class. We prove that there exists an effective mechanical s…

On the convexity of the KdV Hamiltonian

Thomas Kappeler, Alberto Maspero, Jan-Cornelius Molnar +1

We prove that the nonlinear part $H^{*}$ of the KdV Hamiltonian $H^{k d v}$ , when expressed in action variables $I = (I_{n})_{n \geq 1}$ , extends to a real analytic function on the pos…
