Comptes Rendus. Mathématique, Tome 354 (2016) no. 2, pp. 195-200.

Dans cette Note, nous apportons une réponse positive à la conjecture de Kaiser sur les centres ε-positifs des courbes convexes, puis nous en présentons deux applications.

In this paper we will first give a positive answer to Kaiser's conjecture on ε-positive centers for convex curves and then present its two applications.
