Recovery of singularities in a fourth-order operator on the line from limited data

T Tyni, M Harju, V Serov - Inverse Problems, 2016 - iopscience.iop.org
We consider a differential operator of order four with three coefficients which may be
complex valued. We prove that the Born approximation can be used efficiently to recover …
