Pseudodifferential analysis, automorphic distributions in the plane and modular forms

Pseudodifferential analysis, introduced in this book in a way adapted to the needs of number theorists, relates automorphic function theory in the hyperbolic half-plane ? to automorphic distribution theory in the plane. Spectral-theoretic questions are discussed in one or the other environment: in the latter one, the problem of decomposing automorphic functions in ? according to the spectral decomposition of the modular Laplacian gives way to the simpler one of decomposing automorphic distributions in R 2 into homogeneous components. The Poincaré summation process, which consists in building automorphic distributions as series of g -transforms, for g E SL (2 ; Z), of some initial function, say in S (R 2 ), is analyzed in detail. On ?, a large class of new automorphic functions or measures is built in the same way: one of its features lies in aninterpretation, as a spectral density, of the restriction of the zeta function to any line within the critical strip. Several new ideas are far from being pushed to the end, and call for many possible generalizations, only hinted at.The book is addressed to a wide audience of advanced graduate students and researchers working in analytic number theory or pseudo-differential analysis. Presents pseudodifferential analysis tailored to the needs of number theorists Besides containing novel features of the Weil calculus, it may constitutean approach to non-holomorphic modular form theory, suitable for analysts. Gives hints to possible generalizations of the construction of new classes of automorphic functions. Explains how and why pseudodifferential analysis should be developed in the adelic setting. Series of Kloosterman sums, some of which are of a novel kind, play a major. role in several parts of the book INDICE: Introduction. The Weyl calculus. The Radon transformation and applications.
