摘要: 用测度理论和截断方法, 讨论一类具权函数的退化椭圆方程解的性质, 结果表明, 该问题的逼近解一致趋于零.

关键词: 权函数, 截断函数, 加权Sobolev空间, 退化椭圆方程

Abstract: We used the measure theory and truncation method to disscuss the properties of solutions for a class of degenerate elliptic equations with weighted functions. The result shows that the approximated solutions of the problem tend to zero uniformly.

Key words: weighted Sobolev space, degenerate elliptic equation, weighted function, truncation function
