Semielliptic Pseudodifferential Operators
Journal of Functional Analysis, 1995 On étudie la régularité des solutions des problèmes aux limites associés à un opérateur pseudo-différentiel semi-elliptique de la forme \[ P = D^\mu_t + \sum_{1 \leq j \leq \mu} p_j (x,t,D_x) D_t^{\mu - j}, \] \(t \in [0,T)\), \(x \in \omega\) ouvert de \(\mathbb{R}^n\), où \(p_j (x, t,D_x)\) est un opérateur pseudo-différentiel en \(x\), de closse \({\

Pseudodifferential operators are a generalisation of partial differential operatorsvia Fourier transforms. In this thesis, we first introduce the pseudodifferential operatorsassociated with the classical Kohn-Nirenberg symbols. Some of their importantproperties are proven thereafter, including asymptotic expansion, composition, adjointsand parametrices

Classes of spatially inhomogeneous pseudodifferential operators. [PDF]
Proc Natl Acad Sci U S A, 1973 One can obtain sharp information on a pseudodifferential operator p (x,D) by embedding the symbol p in a symbolic calculus specially designed to reflect the behavior of p . We sketch the development of symbolic calculi arising in this connection, and use our results to

Pseudodifferential Operators on Modulation Spaces
Journal of Mathematical Analysis and Applications, 2001 Pseudodifferential operators on modulation spaces are considered. The author gives a fundamental connection between certain classes of pseudodifferential operators and Hille-Tamarkin operators. As an application, compactness and summability of the eigenvalues of pseudodifferential operators acting on the modulation spaces is studied.

Pseudodifferential operators with homogeneous symbols.
Michigan Mathematical Journal, 1999 The authors define homogeneous symbols as symbols \(a(x,\xi)\) in \(C^\infty(\mathbb{R}^n\times (\mathbb{R}^n/0))\) satisfying \[ |D^\alpha_x D^\beta_\xi a(x,\xi)|\leq C_{\alpha\beta}|\xi|^{m- |\beta|+|\alpha|} \] for all \(\alpha\), \(\beta\), with constants \(C_{\alpha\beta}\) independent of \(x\in\mathbb{R}^n\), \(\xi\in \mathbb{R}^n/0\).

Magnetic Pseudodifferential Operators
Publications of the Research Institute for Mathematical Sciences, 2007 In previous papers, a generalization of the Weyl calculus was introduced in connection with the quantization of a particle moving in ℝ^n under the influence of a variable magnetic field B

Pseudodifferential operators with completely periodic symbols
, 2023 Motivated by the recent paper of Boggiatto-Garello (J Pseudo-Differ Oper Appl 11:93-117, 2020) where a Gabor operator is regarded as pseudodifferential operator with symbol p(x, \omega) periodic on both the variables, we study the continuity and ...
