Gabor wave packets and evolution operators
Elena Cordero, Fabio Nicola, Luigi Rodino
We perform a Gabor analysis for a large class of evolution equations with constant coefficients. We show that the corresponding propagators have a very sparse Gabor matrix, display…
Integral Representations for the Class of Generalized Metaplectic Operators
E. Cordero, F. Nicola, L. Rodino
This article gives explicit integral formulas for the so-called generalized metaplectic operators, i.e. Fourier integral operators (FIOs) of Schrödinger type, having a symplectic m…
On the Schrödinger equation with potential in modulation spaces
Elena Cordero, Fabio Nicola
This work deals with Schrödinger equations with quadratic and sub-quadratic Hamiltonians perturbed by a potential. In particular we shall focus on bounded, but not necessarily smoo…
Triangular Subgroups of and Reproducing Formulae
Elena Cordero, Anita Tabacco
We consider the (extended) metaplectic representation of the semidirect product between the Heisenberg group and the symplectic…
