If there are no objections I would delete this section, because it is extra now, the necessary information is given before.Eozhik (talk)11:51, 29 February 2020 (UTC)[reply]
The article may serve as a handy reference for pure mathematicians, but for a wider audience I recommend that you add simple, concrete example(s). For example, "In the 2D Cartesian plane, one mapping of pointP is (0,1), but the consequence of 'dual vector spaces' is ....", or whatever actually matches what this article is trying to say.

This article contains someuseful examples of topological duals which come up in practice.
The last part of the proof is incorrect. In the case where V=R as a vector space over R the last inequality becomes |R|<|R^1|=|R|, which is clearly false.130.237.243.13 (talk)11:45, 21 September 2022 (UTC)[reply]
