This non-implication,
Form 114 \( \not \Rightarrow \)
Form 76,
whose code is 6,
is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 114 | <p> Every A-bounded \(T_2\) topological space is weakly Loeb. (<em>\(A\)-bounded</em> means amorphous subsets are relatively compact. <em>Weakly Loeb</em> means the set of non-empty closed subsets has a multiple choice function.) </p> |
Conclusion | Statement |
---|---|
Form 76 | <p> \(MC_\omega(\infty,\infty)\) (\(\omega\)-MC): For every family \(X\) of pairwise disjoint non-empty sets, there is a function \(f\) such that for each \(x\in X\), f(x) is a non-empty countable subset of \(x\). </p> |
The conclusion Form 114 \( \not \Rightarrow \) Form 76 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
Name | Statement |
---|---|
\(\cal N1\) The Basic Fraenkel Model | The set of atoms, \(A\) is denumerable; \(\cal G\) is the group of all permutations on \(A\); and \(S\) isthe set of all finite subsets of \(A\) |
