WebDec 5, 2024 · And you keep going with the small Veblen ordinal, large Veblen ordinal, Bachmann-Howard ordinal, etc. I think going on like this, you never get beyond the Church–Kleene ordinal. I think my question is basically whether there is a systematic way of naming all the ordinals up to the Church–Kleene ordinal. WebTo make this precise, we introduce ordinal notations. A notation system for ordinals assigns ordinals to natural numbers in a way that reﬂects how each ordinal is built up from its predecessors. Our exposition in this part follows Rogers [1987]. Deﬁnition 19.2 (Kleene): A system of notation S is a mapping ν S from a set D

The smallest non-recursive ordinal is the Church Kleene ordinal, , named after Alonzo Church and S. C. Kleene; its order type is the set of all recursive ordinals. Since the successor of a recursive ordinal is recursive, the Church–Kleene ordinal is a limit ordinal . See more In mathematics, particularly set theory, non-recursive ordinals are large countable ordinals greater than all the recursive ordinals, and therefore can not be expressed using ordinal collapsing functions See more Recursively "x" ordinals, where "x" typically represents a large cardinal property, are kinds of nonrecursive ordinals.
