The name of Arc simple arc Jordan arc should be changed, but I'm not sure what to. Confusingly, there are already entries for Arc, Jordan arc and simple arc. There are four articles where there should be at most three, but I don't know enough about the area to say where to draw the line and how these should be merged. TBloom 10:47, 24 April 2012 (CEST)

- On actually reading the definitions, it seems like Arc simple arc Jordan arc, Jordan arc and simple arc should all be merged under either the name of Jordan arc or simple arc. TBloom 10:48, 24 April 2012 (CEST)

- Yes. And I wonder why "arc" is just a notion of discrete geometry (as I see in our "Arc" article). Is it the standard terminology? Or should it be something like "arc (projective geometry over a finite field)"? As for me, "arc" should be rather a disambiguation page with links to these (ultimately, two? the other being "arc (topology)"?) articles. --Boris Tsirelson 12:43, 24 April 2012 (CEST)

- That sounds reasonable. Wikipedia, for example, has Arc (geometry) and Arc (projective geometry). Unless somebody weighs in otherwise, I'll make two arc articles and merge them accordingly, and make the existing Arc page a disambiguation page. Shall I go with Arc (topology) and Arc (projective geometry)? TBloom 12:55, 24 April 2012 (CEST)

- I am just a probabilist, – not an expert in any of these two topics. Maybe experts can fine-tune the titles better? On the other hand, they will be able to do so afterwards (and move the articles). --Boris Tsirelson 14:47, 24 April 2012 (CEST)

Arc simple arc Jordan arc, Jordan arc and simple arc have now been merged into Arc (topology) and Arc has been moved to Arc (projective geometry). Arc is now a disambiguation page. If somebody knowledgeable could have a look at my disambiguation descriptions and my merging, that'd be great. Could somebody who can please delete Arc simple arc Jordan arc, Jordan arc and simple arc? TBloom 10:20, 25 April 2012 (CEST)

- Only Ulf can delete; ask him there. --Boris Tsirelson 13:02, 25 April 2012 (CEST)
