Abstract:
Let $L$ be a second order, (variable coefficient) elliptic differential operator and let $u\in B^{p,p}_\alpha (\Omega )$, $1<p<\infty$, $\alpha >0$, satisfy $Lu=0$ in the Lipschitz domain $\Omega$. We show that $u$ can exhibit more regularity on Besov scales for which smoothness is measured in $L^\tau$ with $\tau <p$. Similar results are valid for functions representable in terms of layer potentials.References
