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

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 The calculus we have given here is exact modulo operators in L1 and symbols in S1. However, it is complicated by the presence of in nite sums in (2.1.14). Now the terms with 6= 0 in these sums are of order m+ 1 2ˆ. 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): FOURIER INTEGRAL OPERATORS. II BY J. J. DUISTERMAAT and L.

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. 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.
