This non-implication,
Form 65 \( \not \Rightarrow \)
Form 174-alpha,
whose code is 6,
is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 65 | <p> <strong>The Krein-Milman Theorem:</strong> Let \(K\) be a compact convex set in a locally convex topological vector space \(X\). Then \(K\) has an extreme point. (An <em>extreme point</em> is a point which is not an interior point of any line segment which lies in \(K\).) <a href="/books/23">Rubin, H./Rubin, J. [1985]</a> p. 177. <p> |
Conclusion | Statement |
---|---|
Form 18 | <p> \(PUT(\aleph_{0},2,\aleph_{0})\): The union of a denumerable family of pairwise disjoint pairs has a denumerable subset. </p> |
The conclusion Form 65 \( \not \Rightarrow \) Form 174-alpha then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:

\(\cal N2\) The Second Fraenkel Model | The set of atoms \(A=\{a_i : i\in\omega\}\) is partitioned into two element sets \(B =\{\{a_{2i},a_{2i+1}\} : i\in\omega\}\). \(\mathcal G \) is the group of all permutations of \( A \) that leave \( B \) pointwise fixed and \( S \) is the set of all finite subsets of \( A \). |
