Partial data problems in scalar and vector field tomography
Joonas Ilmavirta, Keijo Mönkkönen
We prove that if is some constant coefficient partial differential operator and is a scalar field such that vanishes in a given open set, then the integrals of $…

Boundary rigidity for Randers metrics
Keijo Mönkkönen
If a non-reversible Finsler norm is the sum of a reversible Finsler norm and a closed 1-form, then one can uniquely recover the 1-form up to potential fields from the boundary dist…
