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

We give here a second proof of Mazur's conjecture on higher Heegner points, using a proven case of the André–Oort conjecture as a substitute for the main ingredient of our first proof [1], a theorem of M. Ratner. To cite this article: C. Cornut, C. R. Acad. Sci. Paris, Ser. I 334 (2002) 1039–1042. 相似文献

This paper deals with codimension one (may be singular) foliations on compact Kälher manifoldswhose conormal bundle is assumed to be pseudo-effective. Using currents with minimal singularities, we show that one can endow the space of leaves with a metric of constant non positive curvature wich may degenerate on a “rigidly” embedded invariant hypersurface. 相似文献

We define the index of composition λ(n) of an integer n ⩾ 2 as λ(n) = log n/log γ(n), where γ(n) stands for the product of the primes dividing n, and first establish that λ and 1/λ both have asymptotic mean value 1. We then establish that, given any ɛ > 0 and any integer
k ⩾ 2, there exist infinitely many positive integers n such that . Considering the distribution function F(z,x) := #{n < x : λ(n) > z}, we prove that, given 1 < z < 2 and ɛ > 0, then, if x is sufficiently large,
this last inequality also holding if z ⩾ 2. We then use these inequalities to obtain probabilistic results and we state a conjecture. Finally, using (*), we show
that the probability that the abc conjecture does not hold is 0. 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

In this paper we prove the global existence and uniqueness of the solutions of the 3-dimensional Navier-Stokes equations with small initial data in spaces which Hδ in the i-th direction, δ1+δ2+δ3=½,½< δi <½ and in a space which is L2 in the first two directions and B2,1½ in the third direction, where H and B (respectively) denote the usual homogeneous Sobolev and Besov (respectively) spaces. 相似文献
