| Virial identity and weak dispersion for the magnetic Dirac equation (2009) | |||||||||||||
Abstract | |||||||||||||
| 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 Strichartz estimates which are optimal from the decay point of view. We also prove a Hardy-type inequality for the perturbed Dirac operator. | |||||||||||||
