This non-implication,
Form 379 \( \not \Rightarrow \)
Form 149,
whose code is 4, is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 8 | <p> \(C(\aleph_{0},\infty)\): </p> |
Conclusion | Statement |
---|---|
Form 144 | <p> Every set is almost well orderable. </p> |
The conclusion Form 379 \( \not \Rightarrow \) Form 149 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
Name | Statement |
---|---|
\(\cal M40(\kappa)\) Pincus' Model IV | The ground model \(\cal M\), is a model of \(ZF +\) the class form of \(AC\) |
\(\cal N38\) Howard/Rubin Model I | Let \((A,\le)\) be an ordered set of atomswhich is order isomorphic to \({\Bbb Q}^\omega\), the set of all functionsfrom \(\omega\) into \(\Bbb Q\) ordered by the lexicographic ordering |
\(\cal N40\) Howard/Rubin Model II | A variation of \(\cal N38\) |
