The Analysis of Linear Partial Differential Operators IV: Fourier Integral Operators v. 4: Hormander, Lars: Amazon.sg: Books The theory of pseudo differential operators, discussed in § 1, is well suited for investigating various problems connected with elliptic differential equations. However, this theory fails to be adequate for studying equations of hyperbolic type, and one is then forced to examine a wider class of operators, the so-called Fourier integral operators (Egorov [1975], Hormander [1968, 1971, 1983 As announced in [12], we develop a calculus of Fourier integral G-operators on any Lie groupoid G. For that purpose, we study convolability and invertibility of Lagrangian conic submanifolds of the symplectic groupoid T * G. We also identify those Lagrangian which correspond to equivariant families parametrized by the unit space G (0) of homogeneous canonical relations in (T * Gx \\ 0) x (T AbeBooks.com: The Analysis of Linear Partial Differential Operators IV: Fourier Integral Operators (Grundlehren Der Mathematischen Wissenschaften) (9780387138299) by Hormander, Lars and a great selection of similar New, Used and Collectible Books available now at great prices.

The class of Fourier integral operators contains differential operators as well as classical integral operators as special cases. A Fourier integral operator is given by: Fourier integral operators, the calculus of transposes for bilinear operators does not follow from the linear results by doubling the number of dimensions. Boundedness results cannot be obtained in this fashion either. The essential obstruction is the fact that the integral of a function of two n-dimensional variables (x;y) 2R2n yields was the publication of H˜ormander’s 1971 Acta paper on Fourier integral operators. This globalized the local theory from his 1968 paper, and in doing so systematized some important ideas of J. Keller, Yu. Egorov, and V. Maslov.
