Abstract
In this work, we develop a global calculus for a class of Fourier integral ope-\\rators with symbols $a(x,\xi)$ having exponential growth in $\R^{2n}_{x,\xi}.$ The functional frame is given by the spaces of type S of Gelfand and Shilov. As an application, we construct a parametrix and prove the existence of a solution for the Cauchy problem associated to SG-hyperbolic operators with one characteristic of constant multiplicity.File in questo prodotto:
