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