We prove Skolem's conjecture for the exponential Diophantine equation a n + t b n = ± c n under some assumptions on the integers a , b , c , t . In particular, our results together with Wiles' theorem imply that for fixed coprime integers a , b , c

In discrete tomography, ghosts represent indeterminate locations of a reconstruction when there is insufficient projection information to admit a unique solution. Our previous work presented maximal ghosts, which are tilings of $$2^N$$ connected poin

Discrete tomography reconstructs an image of an object on a grid from its discrete projections along relatively few directions. When the resulting system of linear equations is under-determined, the reconstructed image is not unique. Ghosts are array

Extending earlier research of Erdos and Graham, we consider the problem of products of factorials yielding perfect powers. On the one hand, we describe how the representability of ℓ-th powers behaves when the number of factorials is smaller than, e

This paper aims to show two things. Firstly the importance of Alan Baker's work on linear forms in logarithms for the development of the theory of exponential Diophantine equations. Secondly how this theory is the culmination of a series of greater a

Tomography is the theory behind scans, e.g. MRI-scans. Most common is continuous tomography where an object is reconstructed from numerous projections. In some cases this is not applicable, because the object changes too quickly or is damaged by maki

We present an algorithm that for any given rectangular grid A ∈ Z 2 and set of directions D computes in linear time the values of any function f : A → R outside the convex hull of the union of the switching domains from its line sums in the direc
