具有低阶非线性扰动的分数阶Laplace方程的反问题

Inverse problems for the fractional Laplace equation with lower order nonlinear perturbations

Ru-Yu Lai, Laurel Ohm

摘要:

研究了具有多个低阶非线性项的分数阶Laplace方程的反问题.我们证明了正问题是适定的,反问题是唯一可解的。更具体地说,在适当的设置下,未知的非线性可以从外部测量唯一地确定。

英文摘要:

We study the inverse problem for the fractional Laplace equation with multiple nonlinear lower order terms. We show that the direct problem is well-posed and the inverse problem is uniquely solvable. More specifically, the unknown nonlinearities can be uniquely determined from exterior measurements under suitable settings.
