Chapter I seems to have been the basis for the paper ”Pseudo-diﬀerential operators and hypoelliptic equations”, Proceedings of the AMS Symposium ”Singular in-tegrals” 1966. 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 2014-04-08 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.

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. Symbol of a pseudo-differential operator. Hormander property and principal symbol.

The result is applied to give criteria for the ellipticity and the global hypoellipticity of pseudo-differential operators in terms of their matrix-valued full symbols. Several examples of the first and second order globally hypoelliptic differential equations (where, of course, every differential operator is pseudodifferential). On the other hand, many problems can be solved more simply by posing them simultaneously for differential and pseudodifferential operators (this, in particular, will become clear in the present article).

$\begingroup$ I don't think what I suggest above works for a pseudodifferential operator, but it does work for a differential operator. But if you know how to define what a pesudodifferential operator is without using co-ordinates, that might provide a hint on how to isolate the symbol from the operator. $\endgroup$ – Deane Yang Sep 20 '11 at 18:54 We consider two types of multilinear pseudodifferential operators.

Boundedness properties for pseudodifferential operators with symbols in the bilinear Hörmander classes of sufficiently negative order are proved. The results are obtained in the scale of Lebesgue spaces, and in some cases, end-point estimates involving weak-type spaces and BMO are provided as well. In this paper we give several global characterisations of the Hörmander class Ψm(G) of pseudo-differential operators on compact Lie groups. The result is applied to give criteria for the ellipticity and the global hypoellipticity of pseudo-differential operators in terms of their matrix-valued full symbols. Several examples of the first and second order globally hypoelliptic differential equations (where, of course, every differential operator is pseudodifferential).
