comment Intuition behind functional dependence
@user36772: There is indeed a gap between the idea of functional dependence and your definition of functional independence.

@mathNewFag: Your $S(u,v)$ is not yet correct. Check your computations!

comment I cannot make the mental leap from a vector to a function!
Go back to your linear algebra book and make sure what it is saying. – "Linear independence" is a property of sets of vectors. A one element set $\{v\}$ is linearly independent if $v\ne0$.

comment Is there a notation for being “a finite subset of”?
The notation $\subset\subset$ is very common for "relatively compact", which means "finite" in the discrete case.
