"Topologies on the dual"[edit]
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)
Add simple, concrete example(s)[edit]
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 point P is (0,1), but the consequence of 'dual vector spaces' is ....", or whatever actually matches what this article is trying to say.

Some simple examples of topological duals[edit]
This article contains some useful examples of topological duals which come up in practice.
Cardinal arithmetic 1.2[edit]
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)
