一类分数阶梯度约束的非局部问题

On a class of nonlocal problems with fractional gradient constraint

A. Azevedo, J. F. Rodrigues, L. Santos

摘要:

我们考虑一个希尔伯特和收费的方法来解决分数梯度约束问题的类型$|D^σu|\leq g$,涉及分布分数Riesz梯度$D^σ$,$0<σ<1$,扩展以前的结果的存在性的解决方案和拉格朗日乘子的这些非局部问题。我们还证明了他们的收敛$σ\nearrow1$对他们的本地同行的梯度约束$|D u|\leq g$。

英文摘要:

We consider a Hilbertian and a charges approach to fractional gradient constraint problems of the type $|D^σu|\leq g$, involving the distributional fractional Riesz gradient $D^σ$, $0<σ<1$, extending previous results on the existence of solutions and Lagrange multipliers of these nonlocal problems. We also prove their convergence as $σ\nearrow1$ towards their local counterparts with the gradient constraint $|D u|\leq g$.
