  • Invariant distributions, Beurling transforms and tensor tomography in higher dimensions 

    Paternain, Gabriel Pedro; Salo, Mikko; Uhlmann, Gunther (SpringerMathematische Annalen, 2015-02-01)
    In the recent articles [PSU13, PSU14c], a number of tensor tomography results were proved on two-dimensional manifolds. The purpose of this paper is to extend some of these methods to manifolds of any dimension. A central ...

  • The X-ray transform for connections in negative curvature 

    Guillarmou, Colin; Paternain, Gabriel Pedro; Salo, Mikko; Uhlmann, Gunther (SpringerCommunications in Mathematical Physics, 2015-11-23)
    We consider integral geometry inverse problems for unitary connections and skew-Hermitian Higgs fields on manifolds with negative sectional curvature. The results apply to manifolds in any dimension, with or without boundary, ...
