WebIf addition is the first hyperoperation, multiplication is the second, and the $(\alpha+1)$ th hyperoperation is repeated occurrences of the $\alpha$ th one. Is it possible for a limit ordinal (for example $\omega$) to be $\alpha$ and we use an nth term in its fundamental sequence as the $\alpha$.I don’t know if that’s made any sense so here’s an example. WebOrdinal Recursion Theory C. T. Chong National University of Singapore S. D. Friedman1 Massachusetts Institute of Technology 1 Introduction In a fundamental paper, Kreisel and Sacks [1965] initiated the study of “metarecursion theory”, an analog of classical recursion theory where ω is replaced by Church-Kleene ω1, the least non-recursive ...
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 WebThe Church-Kleene ordinal The set of recursive ordinals is an ordinal which is the smallest ordinal which cannot be described in a recursive way (it is not the order type of any recursive well-ordering of the integers). That ordinal is a countable ordinal called the Church-Kleene ordinal, ω1 CK.
