Let $N$ denote the image resolution, and let $q$ satisfy … An iterative algorithm for inverting the ADRT with computational work of order $\mathcal{O}(N^2\log^q N)$ could exist, an…

Katsevich's error estimate conjecture. The error term is $O(\epsilon^{1/2}\ln(1/\epsilon))$ as $\epsilon\to0$.

Convergence conjecture. The proposed algorithm can be used without concern about non-convergence; in particular, the sequence of iterates $\vec{x}^{(k,I+1)}$ is expected to converg…
