On demontre des resultats sur l'extendabilite holomorphe des fonctions holomorphes definies sur deux coins ou plus et pour lesquelles la somme des valeurs limites s'annulent

On the influence of lower order terms for propagation of analytic singularities for operators with constant coefficients

Regularity of solutions of cauchy problems with smooth cauchy data

Fourier integral operators and inhomogeneous Gevrey classes

Fourier integral operators with inhomogeneous amplitude and phase junction are studied in the frame of Gevrey classes. Applications are given to propagation of singularities for a pseudodifferential equation.
