Abstract

If dd is a boundary defining function for the Euclidean unit disk and II denotes the geodesic X-ray transform, for γ(1,1)\gamma\in (-1,1), we study the singularly-weighted X-ray transforms ImdγI_m d^\gamma acting on symmetric mm-tensors. For any mm, we provide a sharp range decomposition and characterization in terms of a distinguished Hilbert basis of the data space, that comes from earlier studies of the Singular Value Decomposition for the case m=0m=0. Since for m1m\ge 1, the transform considered has an infinite-dimensional kernel, we fully characterize this kernel, and propose a representative for an mm-tensor to be reconstructed modulo kernel, along with efficient procedures to do so. This representative is based on a new generalization of the potential/conformal/transverse-tracefree decomposition of tensor fields in the context of singularly weighted L2L^2-topologies.
