Let S = {a, b, c} and consider the poset (P(S), ⊆) where P(S) is the power set of S (set of all subsets of S). 1) Draw the Hasse Diagram of (P(S), ⊆) and draw the Hasse Diagram of a Topological Sorting of (P(S), ⊆). Thank you.
Consider the greater than or equal to relation on {0, 1,2,3,4,5). (a) Construct the Hasse diagram for this relation. (b) Give any maximal, minimal, maximum, minimum elements of the relation.
Show your work, please 4. Partial Orders Let P be the collection of all subsets of X = {a,b,c,d} that have at least two elements. (So {a,c} € P, but {b} P.) Consider the subset relation C as a partial order on P. For example, {a,b} = {a,b,c}. Draw the Hasse diagram, and find any maximum/minimum elements, and maximal/minimal elements.
Problem 1 Let (A,) and (B, 3) be posets. Consider A x B as a poset under the product order - that is, (a, b) = (a',V) if and only if a < d' and b<W.
