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.葡萄糖 发表于 2025-3-25 11:49:03

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.COW 发表于 2025-3-26 05:01:18
