Revisiting the Fermat-type equation $x^{13} + y^{13} = 3 z^{7}$

Nicolas Billerey, Imin Chen, Lassina Dembélé +2

We solve the Fermat-type equation \[ x^{13} + y^{13} = 3 z^7, \qquad \gcd(x,y,z) = 1 \] combining a unit sieve, the multi-Frey modular method, level raising, computations of system…

On Galois inertial types of elliptic curves over $Q_{ℓ}$

Lassina Dembélé, Nuno Freitas, John Voight

We provide a complete, explicit description of the inertial Weil--Deligne types arising from elliptic curves over $Q_{ℓ}$ for $ℓ$ prime.
