Abstract

In this paper we show that the Lp-realization of a vector-valued elliptic boundary value problem (, j) admits a bounded -calculus on Lp(G;E), 1p<∞, provided="" the="" top-order="" coefficients="" of="" are="" hölder="" continuous.="" here="">G denotes a domain in n with compact C2m-boundary and E a Banach space of class . Our proof is based on an abstract perturbation result for operators admitting bounded -calculus and kernel estimates for the solution of (, j).
