Stability for a formally determined Lorentzian inverse problem

Spyridon Filippas, Lauri Oksanen

We consider the inverse problem of recovering a potential , depending on space and time, in the wave equation on a Lorentzian manifold. We prove Lipschitz stabil…

(In)stability results for the Light Ray Transform

Leonard Busch, Sebastián Muñoz-Thon, Lauri Oksanen

We prove quantitative instability results for the light ray transform in the Minkowski setting, and locally in the smooth and Gevrey categories. In the smooth Sobolev setting, we s…

Inverse Scattering for Single Photons in Quantum Optics

Giovanni Covi, Matti Lassas, Medet Nursultanov +3

We study inverse problems for a time-harmonic one-photon model describing the interaction of a single photon with a medium of stationary two-level atoms. After time-harmonic reduct…

An inverse free boundary problem

Cătălin I. Cârstea, Matti Lassas, Jinpeng Lu +2

We study inverse problems for the elliptic and parabolic obstacle problems from boundary measurements. For the classical elliptic obstacle problem with strictly superharmonic obsta…

Fixed angle inverse scattering with non-constant velocity

Lauri Oksanen, Rakesh, Mikko Salo

In this article, we study formally determined inverse problems for wave equations in the presence of a variable sound speed. We prove that by measuring the boundary data of finitel…

Semiglobal uniqueness for the Lorentzian Calderón problem

Lauri Oksanen, Rakesh, Mikko Salo

We prove uniqueness in the Lorentzian Calderón problem in a semiglobal setting, comparing a potentially large perturbation of the Minkowski metric against a small one. Our proof us…
