Abstract

Abstract: Using a pointwise inequality for Sobolev functionsin terms of maximum function to construct a global Lipschitz continuous testing function and using Hardy’s inequality,the author obtains global estimates for very weak solutions to quasi-linear elliptic equation div A(x，Du)+B(x，u)=－div(｜F｜p－2F) satisfying certain conditions listing in the following.

Key words: Hardy&rsquo, s inequality, very weak solution, Lipschitz continuous, global estimate
