Harnack principle for weakly coupled elliptic systems

[摘要] We prove the Harnack inequality for the weakly coupled elliptic system S, where [GRAPHICS] Here {L-k, k = 1,..., N} are second order elliptic operators with Holder continuous coefficients and Q is a matrix-valued function with singular entries. In the case that Q is irreducible, a full Harnack principle is proved. (C) 1997 Academic Press.
