Étude du cas rationnel de la théorie des formes linéaires de logarithmes. (French) [Study of the rational case of the theory of linear forms in logarithms]

Gaudron, Éric

We establish new measures of linear independence of logarithms on commutative algebraic groups in the so-called \emph{rational case}. More precisely, let k be a number field and v_{0} be an arbitrary place of k. Let G be a commutative algebraic group defined over k and H be a connected algebraic sub...

Visual Exploration of (French) Commuter Networks

Chiricota, Yves; Melançon, Guy; Phan Quang, Trung Tien; Tissandier, Patrice

Commuters induce a network structure on the territory linking cities. Geographers study commuter data trying to understand the structure of the network, as a contribution towards urban planning. Our approach is more specifically designed to help geographers identify multiscale phenomenon, reflecting...

On representing the relationship between the mathematical and the empirical

French, S.R.D.; Bueno, O.; Ladyman, J.

We examine, from the partial structures perspective, two forms of applicability of mathematics: at the “bottom” level, the applicability of theoretical structures to the “appearances”, and at the “top” level, the applicability of mathematical to physical theories. We argue that, to accommodate the...

Cop and robber games when the robber can hide and ride

Chalopin, Jérémie; Chepoi, Victor; Nisse, Nicolas; Vaxès, Yann

In the classical cop and robber game, two players, the cop C and the robber R, move alternatively along edges of a finite graph G = (V , E). The cop captures the robber if both players are on the same vertex at the same moment of time. A graph G is called cop win if the cop always captures the robber...
