利用单调性公式研究了分数阶Schr”{o}dinger方程的反问题.给出了正有界势函数与其非局部Dirichlet-to-Neumann映射之间的单调性关系。基于单调性关系,我们可以构造性地证明非局部Calder '{o}n问题的唯一性.其次,我们提供了一种重建方法,在一个给定的领域内的未知障碍。我们的方法与维数ngeq 2无关,只需要分数阶Schr”{o}dinger方程的背景解。
We consider the inverse problems of for the fractional Schr"{o}dinger equation by using monotonicity formulas. We provide if-and-only-if monotonicity relations between positive bounded potentials and their associated nonlocal Dirichlet-to-Neumann maps. Based on the monotonicity relation, we can prove uniqueness for the nonlocal Calder'{o}n problem in a constructive manner. Secondly, we offer a reconstruction method for an unknown obstacles in a given domain. Our method is independent of the dimension $ngeq 2$ and only requires the background solution of the fractional Schr"{o}dinger equation.
