Is it necessary to mention Riemann surfaces in this article at all? It seems that it has nothing to do with domain coloring. Maybe add a section on other methods of visualizing of complex functions? Lahvak 04:39, 17 April 2007 (UTC)

I corrected the unit circle image. Previously the legend for the phase of cyan said "2pi mod 2pi", which was incorrect. I changed it to "pi mod 2pi", which is correct tryptographer (talk) 04:01, 31 December 2007 (UTC)

Complex mapper link broken

External link to Complex Mapper and also author's link are broken. The new site seems to be this: http://alessandrorosa.altervista.org/ —Preceding unsigned comment added by 213.140.14.134 (talk) 10:29, 28 November 2008 (UTC)


self linking and other issues in /Using the third dimension to represent modulus/

I think that the section on /Using the third dimension to represent modulus/ is a self link, because the reference for it goes to User:Hansfbaier's blog here: http://www.hansfbaier.de/wordpress/computers-and-mathematics/ Self-linking aside, I think that 3d extensions to domain coloring are (or should be) beyond the scope of this article for the following reasons: one, most visualizations of domain coloring are expressly 2d, two, we're not talking about Kaehler manifolds here tryptographer Sat Sep 26 09:07:43 EDT 2009

the self-linked content has been deleted tryptographer (talk) 04:27, 29 June 2010 (UTC)

Consistency

I would like to propose, that across all the complex analysis pages featuring domain coloring, that we use <a href="http://code.google.com/p/mpmath/">mpmath</a> to generate the pictures for consistency's sake. tryptographer (talk) 04:01, 18 July 2010 (UTC)

Content/scope edit war?

There seems to be an bit of a war going about some content that would expand the scope of this article a bit, but no discussion here about it. It looks to me like a compromise would be in order, if the new material is sourced. I'd be happy to look at it, but don't want to chase it down across multiple user talk pages. Dicklyon (talk) 16:49, 11 April 2012 (UTC)

@Dicklyon, go ahead, do not care any more. Glenzo999 (talk) 15:47, 4 April 2013 (UTC)
The need for the merge seems obvious to me -- how could it be undesirable? Fgnievinski (talk) 03:05, 5 April 2013 (UTC)

MERGE

I have merged and remerged and reremerged this page. I am tired of this edit war. who ever is doing please stop... ;( Glenzo999 (talk) 16:17, 12 April 2012 (UTC)

Um, you're the one edit-warring over a merge that nobody wants - you've never given a reason why it's necessary. Why not explain yourself? MikeWazowski (talk) 17:24, 12 April 2012 (UTC)

Pictures

The pictures look nice, but for sin(x), why does the color change along the line im(z)=0? sin(x+0y) is real, so shouldnt it be red all along this horizontal line ? — Preceding unsigned comment added by 129.78.233.211 (talk) 03:32, 24 July 2013 (UTC)

sin(x) is real indeed for real x, but it can be either positive or negative depending on what x is, so the argument of the value varies between 0 (red) and π (cyan), except when sin(x)=0, which is where you see the black dots. Double sharp (talk) 04:19, 23 March 2016 (UTC)

First figure caption has an unreadable equation.

On my (firefox) browser, the equation in the first figure caption is clipped. The function is

ƒ(x) =(x2 − 1)(x − 2 − i)2/(x2 + 2 + 2i).

Perhaps you could put refer to this figure in the lede and use TEX format?

I know that adds length to the article. But nobody is saying that it is too long!--guyvan52 (talk) 16:18, 21 December 2014 (UTC)
