Definition talk:Cauchy Sequence

This can be defined the same for a pseudometric space (most theorems about metric spaces hold for pseudometric spaces as well—Kelley works almost exclusively with pseudometric spaces when he deals with such). The most general version is for a uniform space, so we should probably consider adding that, but I don't know how much infrastructure we have for them. --Dfeuer (talk) 20:15, 7 January 2013 (UTC)
