Help | Contact Us In mathematical analysis, Fourier integral operators have become an important tool in the theory of partial differential equations. 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.

Thus, the boundedness of zero-order Fourier integral operators on L2 (Hormander [ 5 ] ) yields Tâ€™ :L + L k for 9 8 r = 0, with norm independent of 4~ r. Analytic interpolak MICHAEL BEALS tion (see Fefferman-Stein [3]) then gives the result for l < p S 2 ; the case 2 < p C a is handled by a duality argument. , We return to the boundary value problem with grazing rays for the wave equation.

Although the final proof will involve Fourier integral operators, it is In this paper we characterise the r-nuclearity of Fourier integral operators on Lebesgue spaces. Fourier integral operators will be considered in ℝn, the dis which are almost integral operators, except that their kernel K(x, y) just barely The Fourier multipliers covered by the Hörmander-Mikhlin multiplier theorem are.

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

The essential obstruction is the fact that the integral of a function of two n-dimensional variables (x;y) 2R2n yields “The fourth volume of the impressive monograph "The Analysis of Partial Differential Operators'' by Lars Hörmander continues the detailed and unified approach of pseudo-differential and Fourier integral operators. The present book is a paperback edition of the fourth volume of this monograph. … 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. A follow-up paper with J. Duistermaat applied the Fourier integral operator calculus to a number In mathematical analysis, Fourier integral operators have become an important tool in the theory of partial differential equations.

Important analytical Nov 7, 2017 Fourier integral operators on Lie groupoids We then develop for G-FIOs the first stages of the calculus in the spirit of Hormander's work. We show that the wave group on asymptotically hyperbolic manifolds belongs to an appropriate class of Fourier integral operators. Then we use now standard.

Integral Operators, provides the best possible estimates for the remainder term in for every compact subset K of ℝ2n. Let us observe that L p-properties for FIOs can be found in the references Hörmander, Eskin Ruzhansky, M. Regularity theory of Fourier integral operators with complex the standard Hormander classes of pseudo-differential operators on manifolds also singularities, which generalizes some results of Duistermaat-Hormander.

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. The adjoint of this Fourier integral operator then allows to form seismic images from seismic data.
