Let $X$ be a Hausdorff locally convex vector space. Recall (my reference is the book of H. Jarchow, *Locally Convex Spaces*. B.G. Teubner, 1981) that we say that $X$ is a *semi-Montel space* if every bounded subset of $X$ is relatively compact (equivalently, every closed and bounded subset of $X$ is compact), and a *Montel space* if it is semi-Montel and satisfy one (hence all) of the following conditions (equivalent under the semi-Montel hypothesis, see Proposition 11.5.1, pp. 230 of Jarchow's book):

- $X$ is reflexive;
- $X$ is barrelled;
- $X$ is quasi-barrelled.

It is known that the strong dual of a Montel space is also Montel (Jarchow, Proposition 11.5.4, pp. 230-231). In the proof of Theorem 4.11 (5), pp. 39-40 of the book of A. Kriegl and P.W. Michor, *The Convenient Setting of Global Analysis* (AMS, 1997), it is shown that if $X$ is the strong dual of a Fréchet-Montel space (hence $X$ is a Montel space), then $X$ is a *compactly generated* topological space (also called a *k-space* or a *Kelley space*), i.e. the topology of $X$ is the final topology with respect to the inclusions of compact subsets of $X$. However, it seems to me that the proof of this assertion uses only the fact that $X$ is Montel.

Question:Are Montel spaces compactly generated, or is there a counter-example to this claim?

vector space topologies(i.e. topologies that turn the vector space into a topological vector space), LCTVS topologies etc. So let me ask: What can we say about the TVC or LCTVS topology generated by inclusions of compact sets? $\endgroup$ – Johannes Hahn Oct 15 '14 at 0:26
