Orbit capacity
I've done a few edits on the new article titled Orbit capacity. The title phrase did not appear in boldface type at its first appearance and I changed that. Also, note the use of the "reflist" template.

I'm wondering if it should be made explicit that these measures are probability measures, thus assigning measure 1 to the whole space? Michael Hardy (talk) 22:22, 27 October 2017 (UTC)

Wikipedia usage conventions
Hello.

Please note my recent edits to Small boundary property.
 * It said this:
 * The small boundary property is a property of certain topological dynamical systems.
 * I changed it to say this:
 * In mathematics, the small boundary property is a property of certain topological dynamical systems.
 * One thing that changed is that the phrase small boundary property is now set in bold. (With some exceptions) the title phrase of an article is set in bold at its first appearance, usually in the first sentence (and not always verbatim the way it appears in the title).


 * The first sentence said nothing to acquaint the non-mathematician reader at the outset with the fact that mathematics is what this is about. "Topological dynamical systems" is not a phrase familiar to most non-mathematicians. In some cases, the article's title is enough, but often this needs to be explicit in the first sentence.
 * Ranges of pages and ranges of years and other ranges of numbers use an en-dash, not a hyphen, thus:
 * right: 535–546
 * wrong: 535-546


 * Section titles are set off by _two_ "equals" signs, and subordinate sections have more than two.

I also did some TeX edits, many of which were merely code simplifications, but I also changed $$\phi$$ to $$\varphi$$ since I think the former looks to much like $$\varnothing$$ or $$\emptyset$$ and $$\epsilon$$ to $$\varepsilon$$ because that is what I am accustomed to seeing in books and it seems more legible, and the former looks similar to $$ \in$$.

Much of this is codified in WP:MOS and WP:MOSMATH. Michael Hardy (talk) 18:36, 22 January 2018 (UTC)
