Eisenstein series for GL2(Fq[T]) of weight qk − 1 have zeroes in the Drinfeld upper half-plane. Let F be a fundamental domain for the GL2(A)-action. We determine the number of zeroes in F of these series. Our method is essentially based on an assocíation between Eisenstein series and some functions defined on the edges of the Bruhat-Tits tree. 相似文献

The Lévy transform of a Brownian motion B is the Brownian motion ; denote by Bn the Brownian motion obtained from B by iterating n times the Lévy transform. We establish that the set of all instants t such that Btn=0 for some n, is a.s. dense in the time-axis . To cite this article: M. Malric, C. R. Acad. Sci. Paris, Ser. I 336 (2003). 相似文献

Soient k un corps de caractéristique 0 et X une k[[t]]-variété (éventuellement singulière) plate, purement de dimension relative d. Nous prouvons la rationalité des séries de Poincaré motiviques et de fonctions Zêta dIgusa motiviques, associées à X, à laide de lintégration motivique, du théorème de désingularisation plongée dHironaka, de la théorie des modèles de Néron faibles pour les schémas formels et dun théorème délimination des quantificateurs en théorie des modèles.Revised version: 17 March 2004 相似文献

Let G be a non-Abelian, connected, nilpotent Lie group. Then there exist and such that , contrary to what happens for the group . Moreover, the set of zero divisors is a total subset of . This result is first proven for the Heisenberg group where it is based on the existence of non-trivial Schwartz functions f satisfying for . To cite this article: J. Ludwig et al., C. R. Acad. Sci.

For any subadditive capacity κ on R dominated by a Radon measure, we show that lim κ (χ − δ, χ + ε]/(δ + ε) = dκ (χ) exists for a.a. χ, as δ + ε → 0. Moreover, the Choquet integrals of any positive mesurable g satisfy 相似文献

We extend part of Cannes' work on the Riemann hypothesis to zeta functions of simple algebras. To any irreducible cuspidal automorphic representation of the units in such an algebra we attach, in a natural way, an operator the spectrum of which consists of the critical zeros of its L-function. 相似文献

Sur un sous-corps du corps des complexes, nous associons à un objet de la catégorie des motifs géométriques de Voevodsky un Z-complexe de Hodge mixte de Deligne (Inst Hautes études Sci Publ Math 44:5–77, [D74]). Les filtrations par le poids et de Hodge sont représentées par des foncteurs de troncature, d’un complexe des poids à la Bondarko (J K-Theory 6(3):387–504, [Bo10a]) pour la première et troncature du complexe de De Rham (Lecomte Wach, Manuscr Math 129:75–90, [LW09]) pour l’autre. 相似文献

Let a, c ≥ 0 and let B be a compact set of scalars. We introduce property M* (a, B, c) of Banach spaces X which is a geometric property of Banach spaces generalizing property (M*) due to Kalton. Using M*(a, B, c) with max ¦B¦ + c > 1, we characterize intrinsically a large class of shrinking approximations of the identity, including those related to M-, u-, and h-ideals of compact operators. We also show that the existence of these approximations of the identity is separably determined. As an application, we study ideals of compact and approximable operators. In particular, this provides an alternative unified and easier approach to the theories of M-, u-, and h-ideals of compact operators. 相似文献

Let Θ be a element of the d-dimensional torus $\mathbb{T}$ d andτ the translationτ(x)=x + Θ. When d=1 there existe some partitions of $\mathbb{T}$ 1 which are associated withτ. We prove the existence of partitions of $\mathbb{T}$ d which enjoyed the same kind of properties and whose elements (A i ) i≤n are convex polytopes. We also give a lower bound for the isotropic discrepancy of the sequence (nΘ) nε?. 相似文献

We consider the spectral analysis of a model of networks of Euler-Bernoulli beams. We first give the characteristic equation for the spectrum. Secondly, in some particular situations, we show that the spectrum depends only on the structure of the graph. Thirdly, we investigate the asymptotic behaviour of the eigenvalues by proving the so-called Weyl's formula. 相似文献

We prove that a sequence of faithful and discrete (but not necessarily with finite covolume) representations of a finitely generated group Γ in a semisimple Lie group, that goes to infinity, converges to an isometric action of Γ on an affine building, with controlled germ of apartment stabilizers. 相似文献
