关于Sobolev函数梯度的对称重排

On the symmetric rearrangement of the gradient of a Sobolev function

Vincenzo Amato, Andrea Gentile

AI总结:

本文将带Dirichlet边界条件的Hamilton-Jacobi方程解的经典比较结果推广至具非零边界迹的解,并据此证明了带Robin边界条件的扭转刚度等周不等式及相关泛函的等周不等式。

摘要:

本文将带Dirichlet边界条件的Hamilton-Jacobi方程解的经典比较结果,推广至具非零边界迹的Hamilton-Jacobi方程解。由此,我们证明了扭转刚度的等周不等式(带Robin边界条件)及其他涉及此类边界条件的泛函的等周不等式。

英文摘要:

In this paper, we generalize a classical comparison result for solutions to Hamilton-Jacobi equations with Dirichlet boundary conditions, to solutions to Hamilton-Jacobi equations with non-zero boundary trace. As a consequence, we prove the isoperimetric inequality for the torsional rigidity (with Robin boundary conditions) and for other functionals involving such boundary conditions.
