A set can be represented by listing its elements between braces: A = {1,2,3,4,5}.The symbol ∈ is used to express that an element is (or belongs to) a set, for instance 3 ∈ A.Its negation is represented by WebFeb 19, 2024 · Remark 19.5.1. The difference between maximum and maximal is subtle. A maximum element must be larger than (and hence comparable to) every other element of A, while a maximal element must only be larger than every other element of A to which it is comparable. The distinction between minimum and minimal is similar.

WebSep 5, 2024 · A set together with an ordering relation creates a mathematical structure known as a partially ordered set. Since that is a bit of a mouthful, the abbreviated form poset is actually heard more commonly. If one wishes to refer to a poset it is necessary to identify both the set and the ordering relation. WebTHEOREM 1.1. Let every set of k + 1 elements of a partially ordered set P be de-pendent while at least one set of k elements is independent. Then P is a set sum of k disjoint chains.' It should be noted that the first part of the hypothesis of the theorem is also necessary. For if P is a set sum of k chains and S is any subset containing k + 1

WebA relation from a set A to a set B is a subset of A × B. Hence, a relation R consists of ordered pairs (a, b), where a ∈ A and b ∈ B. If (a, b) ∈ R, we say that is related to , and we also write aRb. Remark We can also replace R by a symbol, especially when one is readily available. This is exactly what we do in, for example, a < b.
