We prove well-posedness results for the Dirichlet problem in
R+n for homogeneous, second order, constant complex
coefficient elliptic systems with boundary data in generalized H\"older spaces
Cω(Rn−1,CM) and in generalized
Morrey-Campanato spaces Eω,p(Rn−1,CM)
under certain assumptions on the growth function ω. We also identify a
class of growth functions ω for which
Cω(Rn−1,CM)=Eω,p(Rn−1,CM)
and for which the aforementioned well-posedness results are equivalent, in the
sense that they have the same unique solution, satisfying natural regularity
properties and estimates.Comment: Minor correction
