3. Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators
Abstract : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. READ MORE
