Unique determination of the shape of a scattering screen from a passive measurement
Emilia Blåsten, Lassi Päivärinta, Sadia Sadique
We consider the problem of fixed frequency acoustic scattering from a sound-soft flat screen. More precisely the obstacle is restricted to a two-dimensional plane and interacting w…

A Borg-Levinson theorem for higher order elliptic operators
Katsiaryna Krupchyk, Lassi Päivärinta
We establish the Borg-Levinson theorem for elliptic operators of higher order with constant coefficients. The case of incomplete spectral data is also considered.

Inverse scattering for the magnetic Schroedinger operator
Lassi Päivärinta, Mikko Salo, Gunther Uhlmann
We show that fixed energy scattering measurements for the magnetic Schroedinger operator uniquely determine the magnetic field and electric potential in dimensions . The…
