Inclusion set theory
WebSet Theory Sets A set is a collection of objects, called its elements. We write x2Ato mean that xis an element of a set A, we also say that xbelongs to Aor that xis in A. If Aand Bare sets, we say that Bis a subset of Aif every element of B is an element of A. In this case we also say that Acontains B, and we write BˆA.

WebHere the underlying set of elements is the set of prime factors of n. For example, the number 120 has the prime factorization = which gives the multiset {2, 2, 2, 3, 5}. A related example is the multiset of solutions of an algebraic equation. A quadratic equation, for example, has two solutions. However, in some cases they are both the same number.

WebThe inclusion-exclusion principle, being a generalization of the two-set case, is perhaps more clearly seen in the case of three sets, which for the sets A, B and C is given by This formula can be verified by counting how many times each region in the Venn diagram figure is included in the right-hand side of the formula. WebDec 27, 2024 · The symbol “⊆” is the set inclusion symbol. If A is not a subset of B, then we write A 6⊆B. Note. For example, we have the subset inclusions N ⊆ Z ⊆ Q ⊆ R ⊆ C (this is Example 2.13(c) in the book). Note. The use of the set inclusion symbol is not universal. Sometimes it is replaced withthesymbol“⊂.”
WebSep 5, 2024 · Theorem 1.1.1 Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B. The set θ = {x: x ≠ x} is called the empty set. This set clearly has no elements. Using Theorem 1.1.1, it is easy to show that all sets with no elements are equal.
WebSorted by: 1. In fact, one way to prove that two sets are equal is to show that they are both subsets/supersets of each other, i.e. A = B ( A ⊂ B) ∧ ( B ⊂ A).
