Higher regularity for parabolic equations based on maximal Lp-Lq spaces
Abstract
In this paper we prove higher regularity for 2m-th order parabolic equations with general boundary conditions. This is a kind of maximal Lp-Lq regularity with differentiability, i.e. the main theorem is isomorphism between the solution space and the data space using Besov and Triebel--Lizorkin spaces. The key is compatibility conditions for the initial data. We are able to get a unique smooth solution if the data satisfying compatibility conditions are smooth.
