We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
202 \(\Rightarrow\) 91 | note-75 |
91 \(\Rightarrow\) 309 | Equivalents of the Axiom of Choice II, Rubin, 1985, theorem 5.7 |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
202: | \(C(LO,\infty)\): Every linearly ordered family of non-empty sets has a choice function. |
91: | \(PW\): The power set of a well ordered set can be well ordered. |
309: | The Banach-Tarski Paradox: There are three finite partitions \(\{P_1,\ldots\), \(P_n\}\), \(\{Q_1,\ldots,Q_r\}\) and \(\{S_1,\ldots,S_n, T_1,\ldots,T_r\}\) of \(B^3 = \{x\in {\Bbb R}^3 : |x| \le 1\}\) such that \(P_i\) is congruent to \(S_i\) for \(1\le i\le n\) and \(Q_i\) is congruent to \(T_i\) for \(1\le i\le r\). |
