| Jul 3, 2017 at 12:40 | comment | added | Emil Jeřábek | It does, in fact, hold for distributive lattices. (I thought at first that one would need an infinitary distributive law, but plain distributivity actually suffices.) | |
| Jul 3, 2017 at 12:14 | comment | added | Emil Jeřábek | I doubt this stands a chance without assuming some form of distributivity. For a simple counterexample, let $\Gamma$ be the diamond lattice with “middle elements” $x,y,z$, and put $A=\{x,y\}$, $B=\{z\}$. Then the left-hand side is $1$, but the right-hand side is $z$. | |
