Higher regularity of solutions to the singular $p$-Laplacean system

Abstract

This paper has been withdrawn by the authors due to a mistake in the proof of the chief result. In particular Theorem 1.3 is correct, while Theorem 1.1 and Theorem 1.2 hold with μ>0 and a suitable restriction on the exponent p. The proof of the modified statements is slightly different.

This paper has been withdrawn
