Definition talk:Chart

Please don't just delete stuff because it's "not presently used and can be re-added". That's against our philosophy. It needs to be put back, under whatever name it needs to be. --prime mover (talk) 23:17, 5 December 2012 (UTC)


 * Coordinate function added into coordinate; I think not worthy of it's own page. Coordinate map is easy to do; but depends on house style: if redirecting a page to chart and adding the definition there fits house style then I suggest doing that, if not I'll make a page.

Dimension
Incidentally, I noticed a form of ambiguity on what is the Euclidean space here, $\R^n$ or $\C^n$; this may be aptly dealt with by separating "complex dimension" and "real dimension" for loc.Eucl. spaces. --Lord_Farin (talk) 23:23, 5 December 2012 (UTC)

Subset?
To be super-technical, "homeomorphism" applies to mappings between spaces, not between subsets, per se. It might be better to leave it alone, for the sake of clarity, or it might be better to call $U$ a subspace and the mapping an "open topological embedding". I don't know what to recommend. --Dfeuer (talk) 18:37, 27 February 2013 (UTC)


 * PW isn't really currently ready to bear the manifold stuff, and the naming of such things shouldn't concern us at the moment. It was plainly me catering for a few easy-to-fix maintenance flags. More advanced stuff is years of work away from where we are now. &mdash; Lord_Farin (talk) 20:13, 27 February 2013 (UTC)
