Moyennes de fonctions arithmétiques de formes binaires
Extending classical results of Nair and Tenenbaum, we provide general, sharp upper bounds for sums of the type ∑ u<m u+v x<n x+y F (Q1(m, n), . . . , Qk(m, n)) where x, y, u, v have comparable logarithms, F belongs to a class defined by a weak form of sub-multiplicativity, and the Qj are arbitrary binary forms. A specific feature of the results is that the bounds are uniform within the F -class...
متن کاملTransport à fiabilité partielle d'images compresséessur les réseaux à commutation de paquets
Although data can have various and multiple constraints, their transport over the Internet are based on TCPand UDP almost exclusively. The end-to-end approach enables the transport service adaptation according tothe type of data as a function of the quality of service provided by networks. Generally speaking, multimediadata are loss-tolerant, so it can afford lossy compression witho...

متن کاملVérification partielle de programmes de contrôle-commande par interprétation abstraite
In the field of static analysis, abstract interpretation based techniques compute over approximations of the set of possible behaviors of programs. These over-approximations give properties on the program that can be used to prove the abscence of some bugs. In the case of control command programs, the behavior of the program depends on the physical environment with which it interacts. This envi...
متن کاملAnneaux de Fonctions p-adiques
We study first-order properties of the quotient rings 9(V)/1 by a prime ideal 9, where 9( V) is the ring of p-adic valued continuous definable functions on some affine p-adic variety V. We show that they are integrally closed Henselian local rings, with a p-adically closed residue field and field of fractions, and they are not valuation rings in general but always satisfy Vx, y(x Iy2 V y IX2). ...
