Abstract (VO)
Résumé

We study the asymptotic (as n→∞) zéro distribution of (1−λ)s_n(z)−λt_n+1(z), where $λ \in ℂ$ , s_n is nth section, t_n is nth tail of the power series of Mittag–Leffler function E_1/ρ of order ρ>1. Our results generalize the results by Edrei, Saff and Varga for the case λ=0.

On étudie la distribution asymptotique (quand n→∞) des zéros de (1−λ)s_n(z)−λt_n+1(z), où $λ \in ℂ$ , s_n est la nème section, t_n est le nème reste du developpement de la fonction de Mittag–Leffler E_1/ρ d'ordre ρ>1. On généralise les résultats obtenus par Edrei, Saff et Varga dans le cas λ=0.
