Langages algébriques de mots biinfinis
Les langages rationnels de mots biinfinis ont CtC rkemment dCfinis et CtudiCs dans divers articles [2,3, lo]; ce sont les langages de mots biinfinis qui appartiennent 5 la fermeture rationnelle biinfinie des langages rationnels de mots finis (c’est B dire qui sont union finie de langages de la forme “ABC” oh A, B, C sont des langages rationnels de mots finis). Nous nous proposons dans ce papier...
متن کاملGraphes canoniques de graphes algébriques
— Concerning algebraic grammars in reduced form, bisimulation in the graph ofleft dérivations is known to be décidable. The quotient of the above graph by ils greatest bisimulation, called the canonical graph, is indeed isomorphic to the graph ofleft dérivations for another algebraic grammar in reduced form, produced by an effective procedure.

متن کاملMoyennes 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 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). ...
