Casimir Operators on Pseudodifferential Operators of Several Variables
نویسندگان
چکیده
We study the actions of the Lie algebra nsl(2,C) of SL(2,C) and the associated Casimir operator on the space of pseudodifferential operators of n variables. We describe the effect of the Casimir operator on a pseudodifferential operator in connection with the symbol map and construct an nsl(2,C)-invariant lifting of the symbol map.

Tau Functions Associated to Pseudodifferential Operators of Several Variables
Pseudodifferential operators of several variables are formal Laurent series in the formal inverses of ∂1, . . . , ∂n with ∂i = d/dxi for 1 ≤ i ≤ n. As in the single variable case, Lax equations can be constructed using such pseudodifferential operators, whose solutions can be provided by Baker functions. We extend the usual notion of tau functions to the case of pseudodifferential operators of ...
متن کاملproperties of M−hyoellipticity for pseudo differential operators
In this paper we study properties of symbols such that these belong to class of symbols sitting insideSm ρ,φ that we shall introduce as the following. So for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of M−hypoelliptic pseudodifferential operators for which define base on this class of symbols. Also we consider maxi...
متن کاملPseudodifferential Operators
The study of pseudodifferential operators emerged in the 1960’s, having its origins in the study of singular integro-differential operators. In fact, Friedrichs and Lax coined the term “pseudodifferential operator” in their 1965 paper entitled “Boundary Value Problems for First Order Operators”. Since that time, pseudodifferential operators have proved useful in many arenas of modern analysis a...
متن کاملWeighted Norm Inequalities for Pseudo-pseudodifferential Operators Defined by Amplitudes
We prove weighted norm inequalities for pseudodifferential operators with amplitudes which are only measurable in the spatial variables. The result is sharp, even for smooth amplitudes. Nevertheless, in the case when the amplitude contains the oscillatory factor ξ 7→ ei|ξ| , the result can be substantially improved. We extend the Lpboundedness of pseudo-pseudodifferential operators to certain w...
متن کاملOn the Fourier analysis of operators on the torus
In this paper we will discuss the version of the Fourier analysis and pseudodifferential operators on the torus. Using the toroidal Fourier transform we will show several simplifications of the standard theory. We will also discuss the corresponding toroidal version of Fourier integral operators. To distinguish them from those defined using the Euclidean Fourier transform, we will call them Fou...
