Nous considérons dans cette Note une classe de fonctions subordonnées à certaines fonctions convexes dans une direction, dont nous déterminons l'enveloppe convexe fermée et les points extrêmes. À l'aide de ces résultats, nous résolvons deux problèmes extrémaux, à savoir des estimations de coefficients et des estimations de moyenne Lp pour les fonctions de cette classe.

In this article, we consider a class of functions that are subordinate to certain convex functions in one direction and determine the closed convex hull and its extreme points for functions in this class. Using these results, we solve two extremal problems, namely, coefficient estimates and Lp mean estimates for functions in this class.
