Rigidity of Travelling Times for Strictly Convex Obstacles in Riemannian Manifolds

Tal Gurfinkel, Lyle Noakes, Luchezar Stoyanov

Let $K$ and $L$ be two disjoint unions of strictly convex obstacles contained within a Riemannian manifold with boundary $S$ of dimension $m \geq 2$ . The sets of travelling times $\…

Uniqueness of Obstacles in Riemannian Manifolds from Travelling Times

Tal Gurfinkel, Lyle Noakes, Luchezar Stoyanov

Suppose that $K$ and $L$ are two disjoint unions of strictly convex obstacles with the same set of travelling times, contained in an $n$ -dimensional Riemannian manifold $M$ (where…

Recovering Obstacles from their Travelling Times

Tal Gurfinkel, Lyle Noakes, Luchezar Stoyanov

Noakes and Stoyanov (2021) introduced a method of recovering strictly convex planar obstacles from their set of travelling times. We provide an extension of this construction for o…
