    Mentioned that VectVect is closed monoidal. Corrected typo about bornological spaces: “cocomplete and cocomplete” -> “complete and cocomplete”.

    Removed the remark saying that bornological vector spaces have “better categorical properties”, but then stating just properties already enjoyed by plain VectVect.

    What was the intention here?

    This is probably a bit off-topic but the only sensible thing I can say is from the point of view of differential categories: From the paper A convenient differential category, the category of “Mackey-complete, separated, topological convex bornological vector spaces and bornological linear maps is a differential category”. They also say that this category is symmetric monoidal closed, complete and cocomplete. I believe (this is not something which is published, and I have not yet worked carefully on this. It is not the same that the better known fact that Vect opVect^{op} is a differential category.) that VectVect is also a differential category but with a map !AB!A \rightarrow B being something called a “polynomial law”. VectVect is also a symmetric monoidal closed, complete and cocomplete category. So as far as being a differential category, monoidal closed, complete and cocomplete are concerned, this category of bornological spaces have the same categorical properties than VectVect but it allows to treat more differentiable functions.

    This may be worthwhile recording at bornological vector space!

    I think that generically any category of structured vector spaces will tend to have less good categorical properties than plain VectVect. The fact worth recording is if such categories are about as well behaved as plain VectVect, not the other way around.

    Did not realize we already had an entry for this. I recorded this references because of their use in and Prop 3.6 in

    Yes, these kinds of propositions are noteworthy not because VectVect would not have these properties, but because it is non-trivial for topological vector spaces to still have such properties.

    (In this vein, currently the whole field of “condensed mathematics” is being developed to make algebra with topological structure retain the good category-theoretic properties of plain algebra.)
