X-ray tomography of one-forms with partial data

Joonas Ilmavirta, Keijo Mönkkönen

If the integrals of a one-form over all lines meeting a small open set vanish and the form is closed in this set, then the one-form is exact in the whole Euclidean space. We obtain…

Unique continuation of the normal operator of the X-ray transform and applications in geophysics

Joonas Ilmavirta, Keijo Mönkkönen

We show that the normal operator of the X-ray transform in $R^{d}$ , $d \geq 2$ , has a unique continuation property in the class of compactly supported distributions. This imm…
