,Ellipticity of Fredholm Pseudo-Differential Operators on ,,(ℝ,),lm on ..(ℝ.), 1 < . < ∞, then the pseudo-differential operator is elliptic. The basic idea is to construct an isometric operator .., λ ∈ ℝ {0}, on L.(ℝ.) in order to prove the ellipticity of the Fredholm pseudo-differential operator with symbol in ... This result is then generalized for arbitrary sy

Type 1,1-Operators Defined by Vanishing Frequency Modulation,patible with negligible operators and stable under vanishing frequency modulation. Elaborating counter-examples of Ching, Hörmander and Parenti-Rodino, type 1, 1-operators with unclosable graphs are proved to exist; others are shown to lack the microlocal property as they flip the wavefront set of a

,Regularity for Quasi-Elliptic Pseudo-Differential Operators with Symbols in Hölder Classes,ype, the authors construct a suitable symbolic calculus and a parametrrx for quasi-elliptic operators; these tools are applied to the study of quasi-elliptic linear partial differential equations with H:older coefficients.

Hyperbolic Systems with Discontinuous Coefficients: Generalized Wavefront Sets, front set of the solution to a transport equation with discontinuous propagation speed and delta functions as initial data. The generalized wave front set turns out to have a more refined and informative structure than the wavefront set of the corresponding distributional limit.
