Some examples on quasi-barrelled spaces
Annales de l'Institut Fourier, Volume 22 (1972) no. 2, p. 21-26

The three following examples are given: a bornological space containing a subspace of infinite countable codimension which is not quasi-barrelled, a quasi-barrelled 𝒟-space containing a subspace of infinite countable codimension which is not 𝒟 -space, and bornological barrelled space which is not inductive limit of Baire space.

On y présente trois exemples : un espace bornologique qui contient un sous-espace de codimension infinie dénombrable non infratonnelé, un 𝒟-espace infratonnelé qui contient un sous-espace de codimension infinie dénombrable qui n’est pas un 𝒟-espace et un espace tonnelé bornologique qui n’est pas limite inductive d’espaces de Baire.
