Abstract:
This note consists of two parts. In the first part we consider the behavior of R-boundedness, R-sectoriality, and property(α) under the interpolation of Banach spaces. In a general setting we prove that for interpolation functors of type h the R-boundedness, the R-sectoriality, and the property(α) preserve under interpolation. In particular, this is true for the standard real and complex interpolation methods. (Partly, these results were indicated in \cite{kalton06}, however, with just a very brief outline of their proofs.) The second part represents an application of the first part. We prove R-sectoriality, or equivalently, maximal Lp-regularity for a general class of parabolic systems on interpolation spaces including scales of Besov- and Bessel-potential spaces over \Rn.
