John域上的加权Korn不等式

Weighted Korn inequality on John domains

Fernando López García

摘要:

在有界欧氏John域上证明了Korn不等式的一个加权形式,其中权是到边界距离的非负幂。在这个定理中,我们还提供了不等式中所涉及的常数的估计,该不等式取决于权重中出现的幂和表征John域的几何条件。这个证明使用了一个基于函数的某种分解的局部到全局的参数。此外,我们还证明了div(u)=f在同类整环上的加权索伯列夫空间中的可解性.在这种情况下,权重是到边界的距离的非正幂。对该问题中出现的常数也作了估计。

英文摘要:

We show a weighted version of Korn inequality on bounded euclidean John domains, where the weights are nonnegative powers of the distance to the boundary. In this theorem, we also provide an estimate of the constant involved in the inequality which depends on the power that appears in the weight and a geometric condition that characterizes John domains. The proof uses a local-to-global argument based on a certain decomposition of functions. In addition, we prove the solvability in weighted Sobolev spaces of div(u)=f on the same class of domains. In this case, the weights are nonpositive powers of the distance to the boundary. The constant appearing in this problem is also estimated.
