This non-implication,
Form 34 \( \not \Rightarrow \)
Form 382,
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 382 | <p> <strong>DUMN</strong>: The disjoint union of metrizable spaces is normal. </p> |
The conclusion Form 34 \( \not \Rightarrow \) Form 382 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
Name | Statement |

\(\cal N57\) The set of atoms \(A=\cup\{A_{n}:n\in\aleph_{1}\}\), where\(A_{n}=\{a_{nx}:x\in B(0,1)\}\) and \(B(0,1)\) is the set of points on theunit circle centered at 0 | The group of permutations \(\cal{G}\) is thegroup of all permutations on \(A\) which rotate the \(A_{n}\)'s by an angle\(\theta_{n}\in\Bbb{R}\) and supports are countable |
