We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
86-alpha \(\Rightarrow\) 8 | clear |
8 \(\Rightarrow\) 361 | Zermelo's Axiom of Choice, Moore, 1982, page 325 |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
86-alpha: | \(C(\aleph_{\alpha},\infty)\): If \(X\) is a set of non-empty sets such that \(|X| = \aleph_{\alpha }\), then \(X\) has a choice function. |
8: | \(C(\aleph_{0},\infty)\): |
361: | In \(\Bbb R\), the union of a denumerable number of analytic sets is analytic. G. Moore [1982], pp 181 and 325. |
