Stability of large periodic solutions of Klein-Gordon near a homoclinic orbit
Benoît Grébert, Tiphaine Jézéquel, Laurent Thomann
We consider a Klein-Gordon equation (KG) on a Riemannian compact surface, for which the flow lets invariant the two dimensional space the solutions independent of the space variabl…

Normalizations with exponentially small remainders for nonautonomous analytic periodic vector fields
Tiphaine Jézéquel
In this paper we deal with analytic nonautonomous vector fields with a periodic time-dependancy, that we study near an equilibrium point. In a first part, we assume that the linear…
