: Uhm, what about + and juxtaposition? They are quite common at least here in Sweden, for boolean algebra.
They're not normally used for sets, though, in my experience (despite the fact that set theory is a boolean algebra:-).
Nope, not for sets. I have rarely seen anything but \cup and \cap for sets. But they are quite often used when working with boolean algebras in general. Martin
