Spectral gaps of potentials in weighted Sobolev spaces,undary conditions. We prove results about correspondencies between the asymptotic behaviour of the spectral gaps of . and the regularity of . in the Gevrey case, among others. The proofs are based on a Fourier block decomposition due to Kappeler &Mityagin, and a novel application of the implicit function theorem.

The Phylogeny of Anguinomorph LizardsIn these lectures we present an extension of Birkhoff normal form theorem to some Hamiltonian PDEs. The theorem applies to semilinear equations with nonlinearity of a suitable class.We present an application to the nonlinear wave equation on a segment or on a sphere. We also give a complete proof of all the results.
