This non-implication,
Form 102 \( \not \Rightarrow \)
Form 30,
whose code is 4, is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 60 | <p> \(C(\infty,WO)\): Every set of non-empty, well orderable sets has a choice function.<br /> <a href="/books/2">Moore, G. [1982]</a>, p 125. </p> |
Conclusion | Statement |
---|---|
Form 30 | <p> <strong>Ordering Principle:</strong> Every set can be linearly ordered. </p> |
The conclusion Form 102 \( \not \Rightarrow \) Form 30 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
Name | Statement |
---|---|
\(\cal N7\) L\"auchli's Model I | \(A\) is countably infinite |
