利用以极大函数表示的有关Sobolev函数的逐点不等式来构造全局的Lipschitz型检验函数得到了:在一定条件下,拟线性椭圆方程 -divA(x,u,Du)=f(x) 在grand Sobolev空间W^θp) 0(Ω)中的很弱解是唯一的.
Using a pointwise inequality for Sobolev functions in terms of maximum function to construct a global Lipschitz continuous test function, the authors obtain uniqueness results for very weak solutions in grand Sobolev space W^θp) 0(Ω) to non-linear elliptic equation -divA(x,u,Du)=f(x) satisfying certain conditions.
