Some simple conditions for univalence
[Quelques conditions simples pour l'univalence]
Comptes Rendus. Mathématique, Tome 354 (2016) no. 1, pp. 7-11.

Nous appliquons le lemme de Ozaki et Umezawa sur les fonctions convexes dans une direction, afin de trouver des conditions suffisantes pour l'univalence et la presque convexité.

We apply Ozaki–Umezawa's lemma on functions that are convex in one direction to find some sufficient conditions for univalence and closeness to convexity.
