I am trying to give a name to this axiom in a definition:
$(X \bullet R) \sqcup (Y \bullet S) \equiv (X \sqcup Y) \bullet (R \sqcup S)$
(for all $X, Y, R, S$) where $\sqcup$ is the join of a lattice and $\bullet$ is some binary operation. It feels related to monotonicity/distributivity but I don't know a standard name for this. Any ideas? So far I have called it "full distributivity". I'd also like to have a name (possibly the same) for this axiom when $\sqcup$ isn't a lattice operation, just some binary operation.
In higher category theory, something very similar is called the interchange law, and is an axiom for a 2-category and similar structures. It's also one of the preconditions for the Eckmann-Hilton argument, where I've also occasionally seen it called the interchange property.
