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“⊂.” 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. Mathematical topics typically emerge and evolve through interactions among many researchers.

WebIn the first paragraph, we set up a proof that A ⊆ D ∪ E by picking an arbitrary x ∈ A. In the second, we used the fact that A ⊆ B ∪ C to conclude that x ∈ B ∪ C.

WebThis set is well defined, since by the theorem above it does not matter what inductive set we start with, we always get the same set N; and there is at least one inductive set by the Axiom of Infinity. Theorem. If S is any inductive set, then N ⊆ S; that is, N is the "smallest" inductive set, in the sense of set inclusion. Proof.

This might sound trivial, but I have a reason for asking: I want to understand if inclusion and exclusion are "commutative" properties, i.e. it doesn't matter in which order you apply them.
