Generalizations of starlike harmonic functions
[Généralisations des fonctions harmoniques étoilées]
Comptes Rendus. Mathématique, Tome 354 (2016) no. 1, pp. 13-18.

Dans cette Note, nous étudions des généralisations des classes de fonctions harmoniques liées aux fonctions de Janowski. En utilisant la théorie des points extrémaux, nous obtenons des estimations de coefficients, des théorèmes de distorsion et des inégalités de moyenne intégrale dans ces classes de fonctions.

In this paper we investigate some generalizations of classes of harmonic functions. By using the extreme points theory we obtain coefficients estimates distortion theorems and integral mean inequalities in these classes of functions.
