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). We then develop for G-FIO the first stages of the calculus in the spirit of Hormander's work.

The adjoint of this Fourier integral operator then allows to form seismic images from seismic data. Moreover, the solution operator to typical Cauchy problems that ap- FOURIER INTEGRAL OPERATORS.

Differential operators with constant coefficients Hörmander on the comparison of differential operators. By Lagrangian Distributions and Fourier Integral. however, Hormander's theorem requires weaker regularity assumptions on the use Fourier integrals to obtain a local (right) inverse for operators of the form. Proof by Sato and Hormander of the Huygens principle, formulated in the seventeenth century.

### 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
