Schrödinger equations with rough Hamiltonians

Elena Cordero, Fabio Nicola, Luigi Rodino

We consider a class of linear Schrödinger equations in R^d with rough Hamiltonian, namely with certain derivatives in the Sjöstrand class . We prove that the correspo…

Wave packet analysis of Schrodinger equations in analytic function spaces

Elena Cordero, Fabio Nicola, Luigi Rodino

We consider a class of linear Schroedinger equations in R^d, with analytic symbols. We prove a global-in-time integral representation for the corresponding propagator as a generali…

On the radius of spatial analyticity for semilinear symmetric hyperbolic systems

Marco Cappiello, Piero D'Ancona, Fabio Nicola

We study the problem of propagation of analytic regularity for semi-linear symmetric hyperbolic systems. We adopt a global perspective and we prove that if the initial datum extend…

Propagation of the Gabor Wave Front Set for Schrödinger Equations with non-smooth potentials

Elena Cordero, Fabio Nicola, Luigi Rodino

We consider Scrödinger equations with real-valued smooth Hamiltonians, and non-smooth bounded pseudo-differential potentials, whose symbols may be not even differentiable. The well…

Phase space analysis of semilinear parabolic equations

Fabio Nicola

We present a wave packet analysis of a class of possibly degenerate parabolic equations with variable coefficients. As a consequence, we prove local wellposedness of the correspond…

Generalized Metaplectic Operators and the Schrödinger Equation with a Potential in the Sjöstrand Class

Elena Cordero, Karlheinz Gröchenig, Fabio Nicola +1

It is well known that the matrix of a metaplectic operator with respect to phase-space shifts is concentrated along the graph of a linear symplectic map. We show that the algebra g…
