Abstract
We investigate the space-time regularity of the local time associated to Volterra-L\'evy processes, including Volterra processes driven by -stable processes for . We show that the spatial regularity of the local time for Volterra-L\'evy process is -a.s. inverse proportionally to the singularity of the associated Volterra kernel. We apply our results to the investigation of path-wise regularizing effects obtained by perturba\Ption of ODEs by a Volterra-L\'evy process which has sufficiently regular local time. Following along the lines of [15], we show existence, uniqueness and differentiablility of the flow associated to such equations.
