"Topologies on the dual"
editIf 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)
editThe 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
editThis article contains some useful examples of topological duals which come up in practice.
Cardinal arithmetic 1.2
editThe 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)
