We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
302 \(\Rightarrow\) 392 | clear |
392 \(\Rightarrow\) 393 | clear |
393 \(\Rightarrow\) 121 | clear |
121 \(\Rightarrow\) 33-n | clear |
33-n \(\Rightarrow\) 47-n | clear |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
302: | Any continuous surjection between compact Hausdorff spaces has an irreducible restriction to a closed subset of its domain. |
392: | \(C(LO,LO)\): Every linearly ordered set of linearly orderable sets has a choice function. |
393: | \(C(LO,WO)\): Every linearly ordered set of non-empty well orderable sets has a choice function. |
121: | \(C(LO,<\aleph_{0})\): Every linearly ordered set of non-empty finite sets has a choice function. |
33-n: | If \(n\in\omega-\{0,1\}\), \(C(LO,n)\): Every linearly ordered set of \(n\) element sets has a choice function. |
47-n: | If \(n\in\omega-\{0,1\}\), \(C(WO,n)\): Every well ordered collection of \(n\)-element sets has a choice function. |
