One-to-one correspondence is bijective. One-to-one is injective. Sorry for the confusion, but this is a standard definition, even if it's one you're not used to

(EDIT: as you keep editing and replying, let me clarify: your confusion is not shared among informed others. Bijective and injective are wonderful terms, yes. One-to-one and one-to-one correspondence are equally informative and useful.)
- tome 16y agoOK, well it's fine to use whatever terminology you like if there are standard definitions, but I think terms including "one-to-one" are unnecessarily confusing, whereas "injective" and "bijective" are perfectly clear.
