[Solutions presque automorphes des équations logistiques avec retard discret et continu]
Comptes Rendus. Mathématique, Volume 355 (2017) no. 12, pp. 1208-1214.

Nous obtenons des conditions suffisantes pour l'existence et l'unicité d'une solution positive et compacte presque automorphe, d'une équation logistique avec retard discret et continu. De plus, nous donnons un contre-exemple à des résultats publiés, qui traitent l'unicité des solutions presque périodiques des équations de type logistique.

We obtain sufficient conditions for the existence and uniqueness of a positive compact almost automorphic solution to a logistic equation with discrete and continuous delay. Moreover, we provide a counterexample to some results in literature which deal with the uniqueness of almost periodic solutions to logistic type equations.
