We have the following indirect implication of form equivalence classes:

62 \(\Rightarrow\) 61 | clear |
61 \(\Rightarrow\) 88 | clear |
88 \(\Rightarrow\) 93 | The Axiom of Choice, Jech, 1973b, page 7 problem 10 |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
36: | Compact T\(_2\) spaces are Loeb. (A space is Loeb if the set of non-empty closed sets has a choice function.) |
62: | \(C(\infty,< \aleph_{0})\): Every set of non-empty finite sets has a choice function. |
61: | \((\forall n\in\omega, n\ge 2\))\((C(\infty,n))\): For each \(n\in\omega\), \(n\ge 2\), every set of \(n\) element sets has a choice function. |
88: | \(C(\infty ,2)\): Every family of pairs has a choice function. |
93: | There is a non-measurable subset of \({\Bbb R}\). |
