I want a symbol for an equivalence relation meaning “on the same hyperbola $xy=c$”.
Is there a standard notation? If not, I'm thinking of something on the tune of
Any idea of a similar sign, or how to build one, by stacking or otherwise, in a way compatible with arXiv, LNCS and AMS environments?

Your symbol is a bit complicated. Since I know of no standard symbol, I suggest this:
which is formed by overlaying two standard symbols (
\asymp
and-
) and requires no additional packages. It looks (to me) like a hyperbolic version of\equiv
(≡
).For general instructions on how to build your own symbols, I suggest this question and its answers.
Note: If you plan to use this symbol in
\scriptstyle
or\scriptscriptstyle
you will need a more complicated version that will adapt to style changes:If you really want the symbol you sketched, you'll probably have to design it yourself. I suggest
tikz
(for designing the symbol) andscalerel
to make it the same size as a symbol of your choice (I picked+
).
