Reconstruction formulas for X-ray transforms in negative curvature
[Inversion de la transformée Rayons X géodésique sur des surfaces à courbure négative]
Annales de l'Institut Fourier, Tome 67 (2017) no. 4, pp. 1353-1392.

Nous dérivons des formules d’inversion pour la transformée Rayons X géodésique de fonctions (appellée I 0 ) et 1-formes à divergence nulle, définie sur des surfaces à courbure negative et bord convexe. Ces formules généralisent celles de L. Pestov et G. Uhlmann dans [28] (valides pour le cas de surfaces dites « simples ») à des cas autorisant des géodésiques captées (i.e., de longueur infinie). Les formules prennent la forme d’équations de Fredholm, dans lesquelles l’analyse des opérateurs d’erreur requiert la dérivation de nouvelles estimées de continuité pour l’operateur normal Π=I 0 * I 0 . Des exemples numériques de reconstructions sont fournis en dernière section.

We give reconstruction formulas inverting the geodesic X-ray transform over functions (call it I 0 ) and divergence-free 1-forms on surfaces with negative curvature and strictly convex boundary. These formulas generalize formulas by L. Pestov and G. Uhlmann previously established for simple surfaces, to cases allowing geodesics with infinite length. Such formulas take the form of Fredholm equations, where the analysis of error operators requires deriving new estimates for the normal operator Π 0 =I 0 * I 0 . Numerical examples are provided at the end.
