Transfinite induction is an extension of mathematical induction to well-ordered sets, for example to sets of ordinal numbers or cardinal numbers. Its correctness is a theorem of ZFC. Meer weergeven Transfinite recursion is similar to transfinite induction; however, instead of proving that something holds for all ordinal numbers, we construct a sequence of objects, one for each ordinal. As an … Meer weergeven Proofs or constructions using induction and recursion often use the axiom of choice to produce a well-ordered relation that can be treated by transfinite induction.

By Theorems 2 and 4 we have in J'2-arithmetic 3-induction a derivable rule and 4-induction independent. Extrapolating backwards in g'-arithmetic we should be able to derive 2-induction and 3-induction should be independent and in

Paul Cohen[19] explicitly attributes his use of the letter V (for the class of all sets) to a 1940 paper by Gödel,[20] although Gödel most likely obtained the notation from earlier sources such as Whitehead and Russell.[18] credit laser holdingsWebTransfinite induction requires proving a base case (used for 0), a successor case (used for those ordinals which have a predecessor), and a limit case (used for ordinals which don't have a predecessor).
