## Merge to circle

I think this article should be merged into Circle. Just because a disk and a circle are mathematically different doesn't mean they can't both be dealt with under the circle topic. It would also enable the business about the confusion between a disk and a circle to be dealt with in one place cleanly. Dmcq (talk) 09:29, 26 February 2010 (UTC)

Nope. Most languages distinguish them, so you proposal would create even a worse interwiki mess than we have today. Incnis Mrsi (talk) 15:55, 27 February 2010 (UTC)
GOOD POINT. Finally someone understands this crisis.--**Najezeko**:) 19:45, 14 November 2010 (UTC)

This article should not be merged. Admittedly, the difference between the disc and circle may seem semantic, it is one which should be acknowledged. I mean, the article needs to cite sources, but it does appear accurate. If you ever refer to a circle instead of a disc, a mathematician will probably correct you, so the difference is more than semantic. ( I'm a math major in undergrad and I personally made the mistake of writing circle, a curve, instead of disc, the planar area inside the curve,and so I had it explained to me the importance of the difference between them by several mathematically knowledgable people).

## Homeomorphic

I'm suggesting that someone put a link to the article "homeomorphic". If there is no such article (I highly doubt there isn't), then please create one.--**Najezeko**:) 19:49, 14 November 2010 (UTC) —Preceding unsigned comment added by Najzeko (talkcontribs)

## region surrounding the closed disk

What is the region surrounding the closed disk called? — Preceding unsigned comment added by Reddwarf2956 (talkcontribs) 06:26, 7 September 2013 (UTC)

“Exterior” should do, or “complement” —Tamfang (talk) 00:23, 20 June 2018 (UTC)
