We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
109 \(\Rightarrow\) 66 | clear |
66 \(\Rightarrow\) 67 |

89 \(\Rightarrow\) 90 | The Axiom of Choice, Jech, 1973b, page 133 |

91 \(\Rightarrow\) 361 | 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 |
---|---|
109: | Every field \(F\) and every vector space \(V\) over \(F\) has the property that each linearly independent set \(A\subseteq V\) can be extended to a basis. H.Rubin/J.~Rubin [1985], pp 119ff. |
66: | Every vector space over a field has a basis. |
67: | \(MC(\infty,\infty)\) \((MC)\), The Axiom of Multiple Choice: For every set \(M\) of non-empty sets there is a function \(f\) such that \((\forall x\in M)(\emptyset\neq f(x)\subseteq x\) and \(f(x)\) is finite). |
89: | Antichain Principle: Every partially ordered set has a maximal antichain. Jech [1973b], p 133. |
90: | \(LW\): Every linearly ordered set can be well ordered. Jech [1973b], p 133. |
91: | \(PW\): The power set of a well ordered set can be well ordered. |
361: | In \(\Bbb R\), the union of a denumerable number of analytic sets is analytic. G. Moore [1982], pp 181 and 325. |
