On the exponential local-global principle

Boris Bartolome, Yuri Bilu, Florian Luca (2013)

Acta Arithmetica

Skolem conjectured that the "power sum" A(n) = λ₁α₁ⁿ + ⋯ + λₘαₘⁿ satisfies a certain local-global principle. We prove this conjecture in the case when the multiplicative group generated by α₁,...,αₘ is of rank 1.

On the Frobenius number of a modular Diophantine inequality

José Carlos Rosales, P. Vasco (2008)

Mathematica Bohemica

We present an algorithm for computing the greatest integer that is not a solution of the modular Diophantine inequality a x mod b x , with complexity similar to the complexity of the Euclid algorithm for computing the greatest common divisor of two integers.

On the generalized Fermat equation over totally real fields

Heline Deconinck (2016)

Acta Arithmetica

In a recent paper, Freitas and Siksek proved an asymptotic version of Fermat’s Last Theorem for many totally real fields. We prove an extension of their result to generalized Fermat equations of the form A x p + B y p + C z p = 0 , where A, B, C are odd integers belonging to a totally real field.
