Different meanings of math terms in different countries Does anyone know of a list of math terms that have (slightly) different meanings in different countries?
For example, "positive" could mean $\geq 0 $ in some places, and "strictly positive" means $>0$ - See Dutch wikipedia page on Positive numbers, which states "In Belgium, it is a number that is greater than or equal to 0".
Another common example is Domain and range, which is even ambiguous at the author level.
I'd also be interested in distinct math terms that different countries use. E.g. Divisors and factors in American vs British school systems, but this will easily get very long.

Since this is now CW, please add an answer for each term that you are aware of.

I find the following very confusing:
French: Groupe de type fini means (in English) a finitely generated group. For instance, for such a group $H_2(G)$ can have infinite rank. 
English: Group of finite type means something much stronger, a group $G$ so that the group ring $ZG$ admits a finite projective resolution by finitely-generated $ZG$-modules. This, in particular, implies that $H_k(G)$ has finite rank for all $k$. Groups of finite type tend to be finitely presented.
