0 votes 0 votes Please verify A) not a lattice since 9 and 12 dont have LUB. B) and C) since it is TOTALLY ORDERED SET,it is a lattice.LUB(a,b) = max(a,b) AND GLB(a,b) = min(a,b) D) is a lattice.LUB(a,b) = a INTERSECTION b & GLB(a,b) = a UNION b.

0 votes 0 votes You're correct about A,B,C A) Not Lattice B & C) Totally ordered set D) A Lattice with LUB(a,b) = a UNION b & GLB(a,b) = a INTERSECTION b. for e.g LUB{(1,2), (2,3)} = {1,2,3} & GLB{(1,2), (2,3)} = {2} Heisenberg answered Mar 23, 2017 Heisenberg comment Share Follow See all 0 reply Please log in or register to add a comment.
