Fourier integral operators generalize pseudodif- Fourier integral operator associated to the perturbed Hamiltonian ﬂow relation. In proving the latter, we make use of the propagation of the semi-classical wave front set results proved in Section 3 below.

By construction, the class of G-FIO contains the class of equivariant families of ordinary Fourier integral operators on the manifolds Gx, x ∈ G (0).

Suitably extended versions are also applicable to hypoelliptic Fourier integral operators with complex valued phase functions. Almost an-alytic functions here permit to give the right geometric descriptions of many quantities in complexi ed phase space and they are useful in the analysis as well. Dynkin [Dy70, Dy72] has used almost analytic functions to develop func-tional calculus for classes of operators. 1971 Fourier integral operators. I. Lars Hörmander.

The class of Fourier integral operators contains differential operators as well as classical integral operators as special cases. A Fourier integral operator operators on Rn can be guessed from those of linear operators in R2n. Though some of our computations are reminiscent of those for linear pseudodiﬀerential operators or Fourier integral operators, the calculus of transposes for bilinear operators does not follow from the linear results by doubling the number of dimensions. Boundedness Hörmander, L. Fourier integral operators. I. Acta Math.

We can therefore obtain a simpler but cruder calculus if from the isomorphism Lm ˆ; (X)=L m+1 2ˆ ˆ; (X) !S ˆ; m(X)=S m+1 2ˆ ˆ; (X): author Hörmander, Lars LU organization. Mathematics (Faculty of Sciences) publishing date 1969 type Working paper publication status We prove the global L p-boundedness of Fourier integral operators that model the parametrices for hyperbolic partial differential equations, with amplitudes in classical Hörmander classes S^m_ 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) ∈ R2n yields In this framework, the forward modeling operator is a Fourier integral operator which maps singularities of the subsurface into singularities of the waveﬁeld recorded at the surface.

I've tried to read the book 'Fourier Integrals in Classical Analysis' written by Sogge, and 'Fourier integral operators by J.J. Duistermaat. But I found it is difficult for me to read them. I wonder that if there is any easier book for me to learn about Fourier integral operators defined on manifolds and in what way the restrictions work.
