Set idea is the maths of infinity and a part of the middle curriculum for arithmetic majors. This booklet blends concept and connections with different components of arithmetic in order that readers can comprehend where of set conception in the wider context. starting with the theoretical basics, the writer proceeds to demonstrate functions to topology, research and combinatorics, in addition to to natural set thought. ideas similar to Boolean algebras, bushes, video games, dense linear orderings, beliefs, filters and membership and desk bound units also are built. Pitched particularly at undergraduate scholars, the strategy is neither esoteric nor encyclopedic. the writer, an skilled teacher, contains motivating examples and over a hundred routines designed for homework assignments, reports and tests. it really is acceptable for undergraduates as a direction textbook or for self-study. Graduate scholars and researchers also will locate it beneficial as a refresher or to solidify their knowing of simple set concept.

Example text

21, it is natural to write α + 1 = α ∪ {α} for ordinals α. We call α + 1 a successor ordinal. Non-zero ordinals that are not successor ordinals are called limit ordinals. 22 Let A be a set of ordinals and β = A. Then β is an ordinal and, for every α ∈ A, α ≤ β. Moreover, if γ is an ordinal and α ≤ γ for every α ∈ A, then β ≤ γ. 12. Recall that supremum is another way to say least upper bound. 22 says that if A is a set of ordinals, then sup(A) = A. If A is a set of ordinals and sup(A) ∈ A, then sup(A) is the maximum element of A, in which case we may write max(A) = sup(A) = A.

12. Recall that supremum is another way to say least upper bound. 22 says that if A is a set of ordinals, then sup(A) = A. If A is a set of ordinals and sup(A) ∈ A, then sup(A) is the maximum element of A, in which case we may write max(A) = sup(A) = A. But not every set of ordinals has a maximum element. For example, sup ({5, 6, 7, . . }) = {5, 6, 7, . . } = ω but ω ∈ {5, 6, 7, . . } , so {5, 6, 7, . . } does not have a maximum element. On the other hand, sup ({5, 6, 7, . . , ω}) = {5, 6, 7, .

14 Let α be an ordinal such that α = 0. Prove that there are unique n, β1 , . . , βn , 1 , . . , n such that • • • • 1 ≤ n < ω, α ≥ β1 > · · · > βn , 1 ≤ i < ω for every i = 1, . . n, and α = ω β1 · 1 + · · · + ω βn · n . This is called Cantor normal form. 15 For each function x : ω → ω, define the support of x to be the set {n < ω | x(n) = 0}. Recall that ω ω = {x | x is a function from ω to ω}. Let A = {x ∈ ω ω | x has finite support}. Given x, y ∈ A such that x = y, there exists a largest n < ω such that x(n) = y(n) and we define x ≺A y ⇐⇒ x(n) < y(n).
