On the inverse problem of finding cosmic strings and other topological defects
Matti Lassas, Lauri Oksanen, Plamen Stefanov +1
We consider how microlocal methods developed for tomographic problems can be used to detect singularities of the Lorentzian metric of the Universe using measurements of the Cosmic…

On the stable recovery of a metric from the hyperbolic DN map with incomplete data
Plamen Stefanov, Gunther Uhlmann, Andras Vasy
We show that given two hyperbolic Dirichlet to Neumann maps associated to two Riemannian metrics of a Riemannian manifold with boundary which coincide near the boundary are close t…

On the microlocal analysis of the geodesic X-ray transform with conjugate points
Sean Holman, Gunther Uhlmann
We study the microlocal properties of the geodesic X-ray transform on a manifold with boundary allowing the presence of conjugate points. Assuming that there are no s…
