Definition talk:Image (Set Theory)

Rolled back definition of image as range because this is covered elsewhere (and belongs on another page anyway). Also bear in mind the variation in the definition of "range" in the first place. This is all documented on "Range" page. --prime mover 00:14, 13 September 2011 (CDT)

Rename suggestion
When suggesting such a radical renaming of such a basic entity as this, it is customary to give a reason why. --prime mover (talk) 11:00, 29 December 2017 (EST)
 * Here's a non-exhaustive list: this page, image of matrix, image in abelian categories and others (see nlab), specific cases (e.g. abelian (pre)sheaves) --barto (talk) (contribs) 12:02, 29 December 2017 (EST)


 * Are they not all instances of images of a mapping? I am concerned about the ever-finer fragmentation of definitions, where instances of basic mathematical objects are being given specific definition pages with ever more specialised titles. We may be in danger of losing track of the general picture of what is actually happening. --prime mover (talk) 12:36, 29 December 2017 (EST)
 * Nope, not instances of image of mapping. Generalizations and similar subsections of also see can do what we're looking for. --barto (talk) (contribs) 13:32, 30 December 2017 (EST)
