ON THE HORMANDER CLASSES OF BILINEAR PSEUDODIFFERENTIAL OPERATORS 3¨ While the composition of pseudodiﬀerential operators (with linear ones) forces one to study diﬀerent classes of operators introduced in [5], previous results in the subject left some level of uncertainty about whether the computation of transposes could still

Abstract: In this paper we give several global characterisations of the Hormander class of pseudo-differential operators on compact Lie groups.

erties of pseudo-differential operators as given in H6rmander [8]. In that paper only scalar pseudo-differential operators were considered, but the exten-sion to operators between sections of vector bundles was indicated at the end of the paper. Briefly the definition is as follows. Let I2 be a Co manifold and E, F, two Co complex vector

Such a characterization has important conse-¨ quences: • The Wiener property: if a pseudodifferential operator (of order 0) is invertible as an operator in L2, its inverse is also a pseudodifferential operator. 2011-12-02 · Abstract: Boundedness properties for pseudodifferential operators with symbols in the bilinear H\"ormander classes of sufficiently negative order are proved.

The study of pseudo-differential operators began in the mid 1960s with the work of Kohn, Nirenberg, Hörmander, Unterberger and Bokobza. They played an influential role in the second proof of the Atiyah–Singer index theorem via K-theory.

First, we prove the boundedness of multilinear pseudodifferential operators with symbols which are only measurable in the spatial variables in INTRODUCTION TO THE WEYL-HORMANDER¨ CALCULUS OF PSEUDODIFFERENTIAL OPERATORS Nicolas Lerner Abstract. In this series of lectures, we introduce the basic elements for the understanding of the Weyl-H¨ormander calculus of pseudodiﬀerential operators.
