We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
15 \(\Rightarrow\) 296 |
The dense linear ordering principle, Pincus, D. 1997, J. Symbolic Logic |
296 \(\Rightarrow\) 404 | clear |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
15: | \(KW(\infty,\infty)\) (KW), The Kinna-Wagner Selection Principle: For every set \(M\) there is a function \(f\) such that for all \(A\in M\), if \(|A|>1\) then \(\emptyset\neq f(A)\subsetneq A\). (See Form 81(\(n\)). |
296: | Part-\(\infty\): Every infinite set is the disjoint union of infinitely many infinite sets. |
404: | Every infinite set can be partitioned into infinitely many sets, each of which has at least two elements. Ash [1983]. |
