The page Algebra has a link to "sigma-algebra" which was marked as unwritten due to the hyphen.
I've made that link point to this entry using the | but I think it's only a short-term fix: "sigma-algebra" is better than "sigma algebra". I've always seen it written with a hyphen (and, indeed, with a Greek lower-case sigma).
How does one go about renaming this page?
You need to make a link to sigma-algebra somewhere, for instance here, then click on the question mark to create the new article, then paste the material from sigma algebra into the new sigma-algebra, and then change sigma algebra so that it only consists of this one line:
#REDIRECT [[Sigma-algebra]]
As you see, it's very exciting and a lot of fun.
