Is the empty set inductive
WitrynaCall 0 = { }, the empty set. Define the successor S(a) of any set a by S(a) = a ∪ {a}. By the axiom of infinity, there exist sets which contain 0 and are closed under the successor function. Such sets are said to be inductive. The intersection of all inductive sets is still an inductive set. This intersection is the set of the natural numbers. Witryna31 gru 2014 · In set theory, everything is a set, so the elements of a set are sets as well, and if $ A $ is a non-empty set, $\bigcap A $ is defined. There is no need to have two …

In order to show that N is inductive we need demonstrate two things: 1) 0 2N, 2) if n 2N, then n+ 2N. For the rst property if I is any inductive set, then by de nition of inductive set, 0 2I.

Witryna9. Usually the axiom of infinity is usually stated: ( ∃ x) ( ∅ ∈ X ∧ ( ∀ y ∈ x) ( y ∪ { y } ∈ x)) see Kunen's Set Theory (2011) or Jech's Set Theory. Any set x which has the above property is called an inductive set. Then ω is defined to be the intersection of all inductive sets. Notice that in this form of the axiom of ...
