Correction text:
Iwould write:
The image of f, denoted f(A), is the subset of B
{f(a)|a \in A} \subseteq B .
If f(A)=B the function is onto or surjective.
To avoid misslinks I would change the word mean (signify, denote ?);
I think univeral agreement is an oximoron, agreement suffice an avoid a misslink.

This notation is being rejected for the reasons given in the message post.
> If f(A)=B the function is onto or surjective.
Surjective already has its own entry, and in fact surjective is already listed in the related words section. It does not need to be defined in the main body text.

I do not make any attempts to avoid superfluous links. Common words like mean cause mislinks in dozens of places, not just here. The correct solution is to attack the source of the problem, not the dozens of symptoms. File a correction upon the "mean" entry and ask for a lowering of the link priority of "mean".
In this case, denote is a better word anyway, so I will use it.

An oxymoron is when two adjacent terms contradict each other. Universal agreement is not an oxymoron; at worst you could argue that is redundant, but there is certainly no contradictory meaning.
Redundancy is sometimes good to emphasize a point. Here I feel that the redundancy is worth the mislink. Again, the proper way to correct a mislink is to file a correction on the mislinked term and ask for the mislinked term (in this case, universal) to adjust their link priority. It is way easier to correct the source entry's link priority than to perpetually chase and clean up after all the dozens of mislinks that a common word like "universal" sprouts. |
