BMO estimates near the boundary for solutions of elliptic systems
Azzeddine El Baraka
Abstract:
In this paper we show that the scale of Sobolev-Campanato spaces
contain the general
BMO-Triebel-Lizorkin spaces
as special cases,
so that the conjecture by Triebel regarding estimates for
solutions of scalar regular elliptic boundary value problems in
spaces (solved in the case
in a previous
work) is completely solved now.
Also we prove that the method used for the scalar case works
for systems, and we give a priori estimates near the boundary for
solutions of regular elliptic systems in the general spaces
containing BMO,
,
and Morrey-Campanato spaces
as special cases. This result extends the work by the author
in the scalar case.
