摘要：

We consider Calderon-Zygmund type estimates for the non-homogeneous p(center dot)-Laplacian system -div(| Du|(p(center dot)-2Du)) = -div(| G|(p(center dot)-2)G), where p is a variable exponent. We show that |G| p(center dot)epsilon L-q(R-n) boolean AND L-1(R-n) implies |Du|(p(center dot)) epsilon L-q(R-n) boolean AND L-1(R-n) for any q >= 1. We also prove local estimates independent of the size of the domain and introduce new techniques to variable analysis. The paper is an extension of the local estimates of Acerbi-Mingione (2005).
