Propagation at the Boundary of Analytic Singularities,We study non elliptic boundary value problems in the framework of microfunctions. We introduce the concept of N-regularity and apply it to the problem of propagation of analytic singularities at the boundary with some possible diffraction.

Singularities of Elementary Solutions of Hyperbolic Equations with Constant Coefficients,Let P(D.) be a hyperbolic operator with constant coefficients with respect to . where x ε R. and ., i.e. its characteristic polynomial P(ξ) satisfies i) P.(θ) ≠ 0 where P. is the principal part of P, and ii) P(ξ−iγθ) ≠ 0 for all ξ ε R. and γ > γ. > 0 where γ. is constant.
