By construction, the class of G-FIOs contains the class of equivariant families of ordinary Fourier integral operators on the manifolds G x, x ∈ G (0). We then develop for G-FIOs the first stages of the calculus in the spirit of Hormander's work.

The essential obstruction is the fact that the integral of a function of two n-dimensional variables (x,y) ∈ R2n yields the form of Fourier integrals Eu(x) = (2π)−n Z e(x,ξ)ˆu(ξ)eihx,ξi dξ. It turns out that indeed one will then be able to determine the function ealmost exactly by algebraic calculations alone. Since no singularities are visible any longer it is natural to talk about pseudo-diﬀerential operators — a term suggested by Friedrichs — instead of 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_ 25 Years of Fomier Integral Operators 1 L.

In 1970 he gave a plenary address (Linear Differential Operators) at the ICM in Nice. He received the 1988 Wolf Prize "for fundamental work in modern analysis, in particular, the application of pseudo differential and Fourier integral operators to linear partial differential equations".

In this paper, we treat the global. L2- This paper follows the notations of Hôrmander [3] to which we refer for the definition and proofs of properties of Fourier integral operators.
