Is there a term for a function from a set to itself? It would be handy.
If the mapping is linear,the application is called linear endomorphism...I'm sure a college student is fed up with these in the linear algebra course.I was...
Yeah, I like self-map better :) So you say F is a self-map of X not on X, right?
On is the appropriate preposition.
I had a feeling you would know.
This is terminology,though,it can vary from one source to another.I told u what i've been taught...
"automorphism" is, generally, a function from A to A that "preserves" whatever algebraic structure A has.
I've learned that that's an endomorphism. An automorphism is an bijective endomorphism.
Oops, you're right. Thanks.
Separate names with a comma.
