Strong topologies on the space of continuous linear maps #

In this file, we define the strong topologies on E →L[𝕜] F associated with a family 𝔖 : Set (Set E) to be the topology of uniform convergence on the elements of 𝔖 (also called the topology of 𝔖-convergence).

The lemma UniformOnFun.continuousSMul_of_image_bounded tells us that this is a vector space topology if the continuous linear image of any element of 𝔖 is bounded (in the sense of Bornology.IsVonNBounded).

We then declare an instance for the case where 𝔖 is exactly the set of all bounded subsets of E, giving us the so-called "topology of uniform convergence on bounded sets" (or "topology of bounded convergence"), which coincides with the operator norm topology in the case of NormedSpaces.

Other useful examples include the weak-* topology (when 𝔖 is the set of finite sets or the set of singletons) and the topology of compact convergence (when 𝔖 is the set of relatively compact sets).

Given E and F two topological vector spaces and 𝔖 : Set (Set E), then strongTopology σ F 𝔖 is the "topology of uniform convergence on the elements of 𝔖" on E →L[𝕜] F.

If the continuous linear image of any element of 𝔖 is bounded, this makes E →L[𝕜] F a topological vector space.
