Usages prescrits ou annoncés, usages observés. Réflexions sur les usages scolaires du numérique par les enseignants

The use of ICT for Education is an extremely complex issue that can and should be analyzed from different perspectives. This article does not intend to cover all of them but, instead, try to address only some of them by developing a high level view showing the contradictions that characterize different official statements and stressing some educational paradoxes. The article describes the Frenc...

Hélène Esnault And

If f : X → S is a fibration of complex connected analytic manifolds, given a point x ∈ X, there is an exact sequence of fundamental groups 0 → π 1 F q , ρ) is an isomorphism, this action defines the coho-mology of the fibers as a local system over the base, resp. a Galois action on the cohomology of ρ over X × Fq ¯ F q. A good analog in algebraic geometry of the topological fundamental group on...

Sublattices of certain Coxeter lattices par Anne - Marie BERGÉ et Jacques MARTINET

In this paper, we describe the sublattices of some lattices, extending previous results of [Ber]. Our description makes intensive use of graphs.

Prioritized Transitions for Updates Marie-odile Cordier and Pierre Siegel

An update operation presupposes that one can predict how the world changes along time. In the absence of a predictive model of evolution, the common sense law of inertia is usually used and justiies the minimal change approach to the frame problem. Instead of relying on an implicit modeling of persistence, we propose to use an explicit modeling of the expected evolution. We rst explain why our ...
