Inverse problems for semilinear elliptic equations with low regularity
David Johansson, Janne Nurminen, Mikko Salo
We show that a general nonlinearity is uniquely determined, possibly up to a gauge, in a neighborhood of a fixed solution from boundary measurements of the corresponding s…

Inverse problems for semilinear elliptic PDE with a general nonlinearity
David Johansson, Janne Nurminen, Mikko Salo
This article studies the inverse problem of recovering a nonlinearity in an elliptic equation from boundary measurements of solutions. Previous results based on…
