The Calderón problem for variable coefficients nonlocal elliptic operators

Tuhin Ghosh, Yi-Hsuan Lin, Jingni Xiao

In this paper, we introduce an inverse problem of a Schrödinger type variable nonlocal elliptic operator $(-\nabla \cdot (A(x)\nabla ){)}^s+q)$, for $0<s<1$. We determine the unknown…
