The Keldys-Fichera Obstacle Problem for Quasilinear Elliptic Equations with Double Degenerate

讨论一类双退化散度型拟线性椭圆型方程的Keldys-Fichera障碍问题,证明了解的存在性.

This paper discusses the Keldys-Fichera obstacle problem for a kind of double degenerate quasilinear elliptic equations in divergence form. Using the weighted Sobolev space and the psudo-monotone operator theory, the existence of solutions to the obstacle problem is obtained.
