Local lens rigidity with incomplete data for a class of non-simple Riemannian manifolds
Let σ be the scattering relation on a compact Riemannian manifold M with non-necessarily convex boundary, that maps initial points of geodesic rays on the boundary and initial directions to the outgoing point on the boundary and the outgoing direction.Let ℓ be the length of that geodesic ray.We study the …
