pitchfork is transversality for smooth manifolds
$X \pitchfork Y$ for submanifolds $X, Y \subseteq Z$ just means that $\forall p \in X \cap Y \;\; T_p X + T_p Y = T_p Z$ .

Are there any Cyrillic characters in use in any field? You'd think with all the great work Russians have done there'd be something but I guess it all get western-washed.

This is probably the best thread to celebrate the cock and balls image that comes up when you google detexify.

Too close to the Greek alphabet, e.g. Cyrillic P vs. Greek pi is essentially the same character, while the Latin alphabet is far enough removed. Perhaps ? would work, but people are just going to read it as "reverse-r" sort of like "reverse E" for "exist".
