A von Staudt-type formula for $z \in Z_{n} [i] \sum z^{k}$

Pedro Fortuny Ayuso, Jose Maria Grau, Antonio Oller-Marcen

In this paper we study the sum of powers in the Gaussian integers $G_{k} (n) := \sum_{a, b \in [1, n]} (a + bi)^{k}$ . We give an explicit formula for $G_{k} (n) (mod n)$ in t…

Fermat test with gaussian base and Gaussian pseudoprimes

Jose M. Grau, Manuel Rodríguez, A. Oller-Marcen +1

The structure of the group $(Z / n Z)^{⋆}$ and Fermat's little theorem are the basis for some of best-known primality testing algorithms. Many related concepts ari…
