Division-ample sets and the Diophantine problem for rings of integers

Gunther Cornelissen, Thanases Pheidas, Karim Zahidi (2005)

Journal de Théorie des Nombres de Bordeaux

We prove that Hilbert’s Tenth Problem for a ring of integers in a number field K has a negative answer if K satisfies two arithmetical conditions (existence of a so-called division-ample set of integers and of an elliptic curve of rank one over K ). We relate division-ample sets to arithmetic of abelian varieties.

Divisors, partitions and some new q-series identities

Alexander E. Patkowski (2009)

Colloquium Mathematicae

We obtain new q-series identities that have interesting interpretations in terms of divisors and partitions. We present a proof of a theorem of Z. B. Wang, R. Fokkink, and W. Fokkink, which follows as a corollary to our main q-series identity, and offer a similar result.

Domaines de Voronoï et algorithme de réduction des formes quadratiques définies positives

David-Olivier Jaquet (1990)

Journal de théorie des nombres de Bordeaux

J’illustre la situation générale par un exemple simple, qui permet de mieux comprendre la géométrie de l’espace des domaines de Voronoï. Ensuite, je donne des résultats généraux sur les arêtes d’un domaine de Voronoï. Finalement, pour les représentants des 15 classes connues de formes parfaites à 7 variables, non équivalentes à E 7 et qui possèdent plus de 28 vecteurs minimaux, je fournis une description détaillée de leurs orbites de voisines.
