Sur une généralisation de la théorie des fractions continues algébriques (suite)

Sur une Généralisation des Coefficients Binomiaux

We prove a recent conjecture of Lassalle about positivity and integrality of coefficients in some polynomial expansions. We also give a combinatorial interpretation of those numbers. Finally, we show that this question is closely related to the fundamental problem of calculating the linearization coefficients for binomial coefficients.

Une approche pour la simulation de comportements émotionnels fondée sur la théorie de la conservation des ressources

The simulation of believable behaviours for virtual agents requires to take human factors such as emotions into account. Most computational models dealing with this subject include emotion categories in their architecture. However, determining the number of categories to use and their influence on behaviour is a difficult task. In this paper, we present a model without emotion categories, cente...

Une généralisation automorphe des nombres de Stirling

Let [n] be theset {1,2, *.. , n> and CT a given permutation in S,, the symmetric group on [n]. The (unsigned) Stirling numbers of the first kind enumerate the permutations on En] with k cycles and those of the second kind give the number partitions of [n] having k blocks. In this paper we compute the number of permutations on [n] with k cycles and the number of partitions on [n] having k blocks...

La dynamique de l’inégalité de la malnutrition des enfants en Afrique. Une analyse comparative fondée sur une décomposition de régression

The dynamics of the Inequality of Children’s Malnutrition in Africa. A Comparative Analysis of a Regression-based Decomposition A comparative analysis for three countries of Africa – Burkina Faso, Cameroon and Togo – of the factors of the relative socioeconomic inequality in stunting of the children, as well as variations of these disparities in time, is proposed. This investigation, mobilizing...
