We present a calculus providing a Curry-Howard correspondence to classical logic represented in the sequent calculus with explicit structural rules, namely weakening...

We show that the colinear factorization properties of QCD amplitudes in the generalized Bjorken regime allow to relate in a simple way the amplitudes of exclusive...

We consider measuring the degree of homogeneity for preference-approval profiles which include the approval information for the alternatives as well as the rankings of...

The prospects for an international agreement within the United Nations Framework on Climate Change (UNFCCC) resulting in a common carbon price ‐ such as a global cap...

This paper analyzes the impact of changes in the winning chances of candidates running for the 2007 French presidential election on abnormal stock returns of firms...

We analyse an optimal control with the following features: the dynamical system is linear, and the dependence upon the control parameter is affine. More precisely we...

In their paper on the ''chasm at depth four'', Agrawal and Vinay have shown that polynomials in m variables of degree O(m) which admit arithmetic circuits of size...

We study the evolution of Wigner measures of a family of solutions of a Schrödinger equation with a scalar potential displaying a conical singularity. Under a...

Abstract. In this paper, I clarify some aspects of the Neapolitan mathematician Nicola Trudi. In particular, I prove that Trudi was a member of the mathematical school...

In courses on integration theory, Chasles property is usually considered as elementary and so "natural" that this is sometimes left to the reader. When the functions...

Ce document présente les détails techniques de l'algorithme de synthese de l'arbre à partir du texte annoté selon le formalisme rhapsodie, ainsi que certains choix...

This work deals with the scattering of acoustic waves by a thin ring that contains many regularly-spaced heterogeneities. We provide and justify a complete description...

Consider the following forest-fire process on a connected graph. Each site of the graph can be either occupied or vacant. A vacant site becomes occupied with rate 1. A...
