# Is there a Math symbol that means “associated”

I am looking for a Math symbol that means "associated" and I don't mean "associated" as something as complicated as isomorphism or anything super fancy.

I am looking for a symbol that means something like "$\triangle ABC$ [insert symbol] $A_{1}$" (as in triangle ABC "associated" with area_{1}) Or want to say something like "The eigenvector associated with the eigenvalue"

You get the idea.

Even if it exists, using such an obscure symbol in the middle of your sentence is not likely to make your idea any more clear. – Austin Mohr Nov 2 '12 at 5:24
I agree. Is it really worth replacing "associated with" with "$\leftrightsquigarrow$" or something? Some things are better expressed with symbols, but probably not this. – wj32 Nov 2 '12 at 5:31
I think the notion of associated with is too vague to have a standard symbol associated with it. – Kevin Carlson Nov 2 '12 at 5:43
One common way you can "associate" things together is to subscript them by the same index. For example, a matrix might have eigenvalues $\lambda_1, \lambda_2, \ldots$ and eigenvectors $v_1, v_2, \ldots$; then everyone understands implicitly that $\lambda_i$ is associated with $v_i$ via the shared index $i$. – Rahul Nov 2 '12 at 6:20

If you want to use such a symbol for association in some sense, you would have to define its meaning precisely first in your exposition. I suggest using $\sim$ for your purpose.
