Virial identity and weak dispersion for the magnetic Dirac equation
Nabile Boussaid, Piero D'Ancona, Luca Fanelli
We analyze the dispersive properties of a Dirac system perturbed with a magnetic field. We prove a general virial identity; as applications, we obtain smoothing and endpoint Strich…

Limiting absorption principle for some long range perturbations of Dirac systems at threshold energies
Nabile Boussaid, Sylvain Golénia
We establish a limiting absorption principle for some long range perturbations of the Dirac systems at threshold energies. We cover multi-center interactions with small coupling co…
