Orlicz-索伯列夫空间中的两障碍问题及其应用

On the Two Obstacles Problem in Orlicz-Sobolev Spaces and Applications

J. F. Rodrigues, R. Teymurazyan

摘要:

证明了T-单调算子的抽象形式的两障碍问题的Lewy-Stampacchia不等式.作为结果,我们对一般的Ladyzhenskaya-Uraltseva型拟线性椭圆算子,包括p(x)-Laplacian型算子,得到了解的$C^{1,α}$正则性的新结果.我们还应用这些不等式得到了N-膜问题的新结果,并利用正则性和单调性得到了(广义)Orlicz-索伯列夫空间中拟变分问题解的存在性.

英文摘要:

We prove the Lewy-Stampacchia inequalities for the two obstacles problem in abstract form for T-monotone operators. As a consequence for a general class of quasi-linear elliptic operators of Ladyzhenskaya-Uraltseva type, including p(x)-Laplacian type operators, we derive new results of $C^{1,α}$ regularity for the solution. We also apply those inequalities to obtain new results to the N-membranes problem and the regularity and monotonicity properties to obtain the existence of a solution to a quasi-variational problem in (generalized) Orlicz-Sobolev spaces.
