We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
113 \(\Rightarrow\) 8 |
Tychonoff's theorem implies AC, Kelley, J.L. 1950, Fund. Math. Products of compact spaces in the least permutation model, Brunner, N. 1985a, Z. Math. Logik Grundlagen Math. |
8 \(\Rightarrow\) 9 | Was sind und was sollen die Zollen?, Dedekind, [1888] |
9 \(\Rightarrow\) 296 | clear |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
113: | Tychonoff's Compactness Theorem for Countably Many Spaces: The product of a countable set of compact spaces is compact. |
8: | \(C(\aleph_{0},\infty)\): |
9: | Finite \(\Leftrightarrow\) Dedekind finite: \(W_{\aleph_{0}}\) Jech [1973b]: \(E(I,IV)\) Howard/Yorke [1989]): Every Dedekind finite set is finite. |
296: | Part-\(\infty\): Every infinite set is the disjoint union of infinitely many infinite sets. |
