Dec 8, 2009 at 23:28 comment added Grue Yeah, "meet" and "join" are rather confusing to me, and I already used one instead of another in the first draft of this question, so I'm sticking to the more... international terms from now on. I meant an infimum of a subset {x,y}, not the whole semilattice.
Dec 8, 2009 at 23:15 comment added Yemon Choi Quibble: when you say every pair of elements has an "infimum", I think you mean "meet". The infimum would be something like the zero of the semilattice
