We determine both the magnetic potential and the electric potential from the exterior partial measurements of the Dirichlet-to-Neumann map in the fractional linear magnetic Calderon problem by using an integral identity. We also determine both the magnetic potential and the nonlinearity in the fractional semilinear magnetic Calderon problem by using a first order linearization.

确定分数磁卡尔德龙问题中的磁势

我们通过使用积分恒等式，从分数线性卡尔德隆问题中狄利克雷到诺依曼映射的外部部分测量确定磁势和电势。我们还通过使用一阶线性化来确定分数半线性磁性 Calderon 问题中的磁势和非线性。
