Maximum and minimum - Wikipedia

WebThe greatest element in a set is defined as the element in the set that is "greater" (defined by any binary relation that forms a preorder, i.e. is reflexive and transitive) than any other element in it. The maximal element is defined as the element that is greater than any element found to be greater than it. WebFrom what I understand (and this could be wrong), the element {1,2,3} of the power set would be both the greatest element (since {1,2,3} is drawn at least as high as every other element in the diagram) and maximal element (since nothing is drawn higher than {1,2,3}). Any help will be greatly appreciated! Thanks. elementary-set-theory order-theory philo buffering

WebJun 19, 2012 · In particular, if a set has both a supremum and a maximum, then they are the same element. The set may also have neither a supremum nor a maximum (e.g., the rationals as a subset of the reals). But if it has only one them, then it has a supremum which is not a maximum and is not in the set. WebLikewise, a greatest element of a partially ordered set (poset) is an upper bound of the set which is contained within the set, whereas a maximal element m of a poset A is an element of A such that if m ≤ b (for any b in A), then m = b.

Please note that there may be multiple elements to which it is not comparable. Web2.3.1 Upper bounds of a set; the least upper bound (supremum) Consider S a set of real numbers. S is called bounded above if there is a number M so that any x ∈ S is less than, or equal to, M: x ≤ M. The number M is called an upper bound for the set S. Note that if M is an upper bound for S then any bigger number is also an upper bound.
