Ray class
I'm planning to introduce Ray class groups here next. Richard Pinch (talk) 09:31, 20 July 2008 (UTC)

 * In the section on ray class groups, the requirements imposed by the infinite places seem to be missing or obscured. —Preceding unsigned comment added by 68.108.211.218 (talk) 01:00, 23 June 2009 (UTC)

Plain english?
Is it possible to explain this concept in a way understandable to anyone unfamiliar with advanced maths? Famousdog (talk) 18:12, 8 September 2008 (UTC)


 * Frankly I've been finding it hard to do that. I learnt about the concept as a post-graduate.  Richard Pinch (talk) 18:14, 8 September 2008 (UTC)


 * Isn't modulus just the remainder? For example, 5 mod 2 is 1. 5 divided by 2 is 2, with a remainder of 1. I really agree, a plain english definition is badly needed. As is, the page is unusable for a majority of people looking at it. Jonberling (talk) 02:47, 19 May 2009 (UTC)


 * No, what you mean is described at modular arithmetic and modulo operation. &mdash;Tobias Bergemann (talk) 07:53, 19 May 2009 (UTC)

I took some 9 years of math and used to understand what modulus meant. After reading that "definition" I knew LESS than I did before reading it. ARghhh! —Preceding unsigned comment added by 98.234.21.242 (talk) 06:39, 15 March 2010 (UTC)


 * This is the term modulus as used in class field theory. Are you sure you're not thinking about its use in modular arithmetic? or even as a synonym of absolute value? Its use here is rather technical, and explained pretty much as plainly as possible. RobHar (talk) 14:59, 15 March 2010 (UTC)


 * The confusion here seems to justify a disamb put at the **very beginning** of the page.18.111.14.184 (talk) 04:03, 20 December 2013 (UTC)
