Modulation Spaces as Symbol Classes for Pseudodifferential Operators
نویسندگان
چکیده
We investigate the Weyl calculus of pseudodifferential operators with the methods of time-frequency analysis. As symbol classes we use the modulation spaces, which are the function spaces associated to the short-time Fourier transform and the Wigner distribution. We investigate the boundedness and Schatten-class properties of pseudodifferential operators, and furthermore we study their mapping properties between modulation spaces.

2 00 6 Pseudodifferential Operators on Locally Compact Abelian Groups and Sjöstrand ’ s Symbol Class
We investigate pseudodifferential operators on arbitrary locally compact abelian groups. As symbol classes for the Kohn-Nirenberg calculus we introduce a version of Sjöstrand’s class. Pseudodifferential operators with such symbols form a Banach algebra that is closed under inversion. Since “hard analysis” techniques are not available on locally compact abelian groups, a new time-frequency appro...

In this work we study some general classes of pseudodifferential operators where the classes of symbols are defined in terms of phase space estimates. Résumé On étudie des classes générales d’opérateurs pseudodifférentiels dont les classes de symboles sont définis en termes d’éstimations dans l’espace de phase.
متن کاملMixed Modulation Spaces and Their Application to Pseudodifferential Operators
This paper uses frame techniques to characterize the Schatten class properties of integral operators. The main result shows that if the coefficients {〈k,Φm,n〉} of certain frame expansions of the kernel k of an integral operator are in l, then the operator is Schatten p-class. As a corollary, we conclude that if the kernel or Kohn-Nirenberg symbol of a pseudodifferential operator lies in a parti...
متن کاملComposition and Spectral Invariance of Pseudodifferential Operators on Modulation Spaces
We introduce new classes of Banach algebras of pseudodifferential operators with symbols in certain modulation spaces and investigate their composition and the functional calculus. Operators in these algebras possess the spectral invariance property on the associated family of modulation spaces. These results extend and contain Sjöstrand’s theory, and they are obtained with new phase space meth...
