310: 現代数学の系譜 雑談 ◆yH25M02vWFhP [] 2025/01/15(水) 18:43:40.92 ID:ZCTGHyhi >>309 それ、下記のWell-ordering theorem ”The well-ordering theorem follows from the axiom of choice as follows.[9]” とほぼ同じでしょ？ おれが、すでに どこかにアップしてあるよ https://en.wikipedia.org/wiki/Well-ordering_theorem Well-ordering theorem Proof from axiom of choice The well-ordering theorem follows from the axiom of choice as follows.[9] Let the set we are trying to well-order be A, and let f be a choice function for the family of non-empty subsets of A. For every ordinal α, define an element aα that is in A by setting aα= f(A∖{aξ∣ξ<α}) if this complement A∖{aξ∣ξ<α} is nonempty, or leave aα undefined if it is. That is, aα is chosen from the set of elements of A that have not yet been assigned a place in the ordering (or undefined if the entirety of A has been successfully enumerated). Then the order < on A defined by aα<aβ if and only if α<β (in the usual well-order of the ordinals) is a well-order of A as desired, of order type sup{α∣aα is defined}. http://rio2016.5ch.net/test/read.cgi/math/1735693028/310
