Distances between measures from 1-dimensional projections as implied by continuity of the inverse Radon transform. (English) Zbl 0555.28005
Distances between measures on $${\mathbb{R}}^ d$$ are determined from distances between their 1-dimensional projections. The method employed involves considering the 1-dimensional projections to be the Radon transform of the measures. Crucial to the main theorem is a continuity result for the inverse Radon transform. Focus is restricted to the Prohorov, dual bounded Lipschitz and $$d_ k$$ metrics which metrize weak convergence of probability measures. These metrics are related to each other and to the Sobolev norms. The $$d_ k$$ results extend from measures to generalized functions.
