We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
109 \(\Rightarrow\) 66 | clear |
66 \(\Rightarrow\) 110 | clear |
110 \(\Rightarrow\) 18 |
The vector space Kinna-Wagner Principle is equivalent to the axiom of choice, Keremedis, K. 2001a, Math. Logic Quart. |
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. |
110: | Every vector space over \(\Bbb Q\) has a basis. |
18: | \(PUT(\aleph_{0},2,\aleph_{0})\): The union of a denumerable family of pairwise disjoint pairs has a denumerable subset. |
