We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 286 \(\Rightarrow\) 40 | S´eminaire d’Analyse 1992, Morillon, 1991b, |
| 40 \(\Rightarrow\) 86-alpha | clear |
| 86-alpha \(\Rightarrow\) 196-alpha |
Successive large cardinals, Bull Jr., E. L. 1978, Ann. Math. Logic |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 286: | Extended Krein-Milman Theorem: Let K be a quasicompact (sometimes called convex-compact), convex subset of a locally convex topological vector space, then K has an extreme point. H. Rubin/J. Rubin [1985], p. 177-178. |
| 40: | \(C(WO,\infty)\): Every well orderable set of non-empty sets has a choice function. Moore, G. [1982], p 325. |
| 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. |
| 196-alpha: | \(\aleph_{\alpha}\) and \(\aleph_{\alpha+1}\) are not both measurable. |
