Rational points on diagonal quartic surfaces

Elsenhans, Andreas-Stephan

We searched up to height $1 0^{7}$ for rational points on diagonal quartic surfaces. The computations fill several gaps in earlier lists computed by Pinch, Swinnerton-Dyer, and Bright…

The Fibonacci sequence modulo $p^{2}$ -- An investigation by computer for $p < 1 0^{14}$

Andreas-Stephan Elsenhans, Jörg Jahnel

We show that for primes $p < 1 0^{14}$ the period length $κ (p^{2})$ of the Fibonacci sequence modulo $p^{2}$ is never equal to its period length modulo $p$ . The investigation involves a…

The discriminant of a cubic surface

Andreas-Stephan Elsenhans, Jörg Jahnel

We construct explicit examples of cubic surfaces over $Q$ such that the 27 lines are acted upon by the index two subgroup of the maximal possible Galois group. This is the simpl…
