Abstract:

We prove the $L^p$-differentiability at almost every point for convolution products on ${\bf R}^d$ of the form $K*\mu$, where $\mu$ is bounded measure and $K$ is a homogeneous kernel of degree $1-d$. From this result we derive the $L^p$-differentiability for vector fields on ${\bf R}^d$ whose curl and divergence are measures, and also for vector fields with bounded deformation.
