Lars Hörmander. Institute for Advanced Study. OPERATORS AND BOUNDARY PROBLEMS, I.A.S. PRINCETON 1965-66 LarsH¨ormander Introduction This series of lectures1 consists of two parts. The ﬁrst is a study of pseudo-diﬀerential operators, and the second consists of applications to boundary problems for elliptic (pseu-do-)differential operators.

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

Bilinear pseudodi erential operators of H ormander type Arp ad B enyi Department of Mathematics Western Washington University Bellingham, WA 98226 ¨ 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 be accomplished within some other bilinear H¨ormander classes. Boundedness properties for pseudodifferential operators with symbols in the bilinear H\"ormander classes of sufficiently negative order are proved. The results are obtained in the scale of Lebesgue operators and bilinear pseudodiﬀerential operators. A bilinear pseudodiﬀerential op-erator T˙ with a symbol σ, a priori deﬁned from S ×S into S′, is given by T˙(f,g)(x) = ∫ Rn ∫ Rn σ(x,ξ,η)fb(ξ)bg(η)eix·(˘+ )dξdη.
