Détermination du taux de salaire réel et analyse néoclassique
1997
L'ambition des Néoclassiques est d'établir une loi scientifique de la répartition qu’ils expliquent essentiellement de deux façons. La première explication est fondée sur la productivité marginale des facteurs déterminée à la production. La seconde est fondée sur l'échange qui détermine la rémunérationdes facteurs ou leur « prix » sur le marché. Or, ces deux déterminations ne sont pas compatibles. La théorie marginaliste écarte d'emblée une grande partie de la réalité économique représentée par les rendements croissants et constants. Elle limite encore son champ en supposant que sur une quantité fixe d’un facteur on peut employer n’importe quelle quantité de facteur variable, hypothèse néce…
Counting Berg partitions via Sturmian words and substitution tilings
2013
We develop the connection of Berg partitions with special substitution tilings of two tiles. We obtain a new proof that the number of Berg partitions with a fixed connectivity matrix is equal to half of the sum of its entries, [12]. This approach together with the formula of Seebold [10], for the number of substitutions preserving a given Sturmian sequence, shows that all of the combinatorial substitutions can be realized geometrically as Berg partitions. We treat Sturmian tilings as intersection tilings of bi-partitions. Using the symmetries of bi-partitions we obtain geometrically the palindromic properties of Sturmian sequences (Theorem 3) established combinatorially by de Luca and Migno…

Modeling multipartite virus evolution: the genome formula facilitates rapid adaptation to heterogeneous environments
2020
Multipartite viruses have two or more genome segments, and package different segments into different particle types. Although multipartition is thought to have a cost for virus transmission, its benefits are not clear. Recent experimental work has shown that the equilibrium frequency of viral genome segments, the setpoint genome formula (SGF), can be unbalanced and host-species dependent. These observations have reinvigorated the hypothesis that changes in genome-segment frequencies can lead to changes in virus-gene expression that might be adaptive. Here we explore this hypothesis by developing models of bipartite virus infection, leading to a threefold contribution. First, we show that th…
