非周期分数阶障碍问题

Aperiodic fractional obstacle problems

Matteo Focardi

摘要:

我们确定的渐近行为(双边)障碍问题的分数能量,而一般的非周期性设置通过伽玛收敛参数。作为进一步的发展,我们考虑的障碍物的随机大小和形状位于点的标准格,和情况下的随机同位障碍物的随机Delone集的点为中心。非局域能量的障碍问题出现在几种物理现象中,我们的结果提供了一阶渐近行为的描述。

英文摘要:

We determine the asymptotic behaviour of (bilateral) obstacle problems for fractional energies in rather general aperiodic settings via Gamma-convergence arguments. As further developments we consider obstacles with random sizes and shapes located on points of standard lattices, and the case of random homothetics obstacles centered on random Delone sets of points. Obstacle problems for non-local energies occur in several physical phenomenona, for which our results provide a description of the first order asympotitc behaviour.
