摘要 本文在一定条件下,运用Hodge分解、Sobolev嵌入定理和Lp中的Minkcwski不等式等,研究二阶拟线性椭圆型方程divA(x,u,u)=0的障碍问题很弱解的性质. Under some conditions,by using Hodge decomoposition,Sobolev imbedding theorems,and Minkcwski inequality in Lp,we consider the property of the very weak solutions of obstacle problem for a quasilinear elliptic equation of second-order div A(x,u,▽u)=0.
