This non-implication,
Form 163 \( \not \Rightarrow \)
Form 68,
whose code is 4, is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 163 | <p> Every non-well-orderable set has an infinite, Dedekind finite subset. </p> |
Conclusion | Statement |
---|---|
Form 146 | <p> \(A(F,A1)\): For every \(T_2\) topological space \((X,T)\), if \(X\) is a continuous finite to one image of an A1 space then \((X,T)\) is an A1 space. (\((X,T)\) is A1 means if \(U \subseteq T\) covers \(X\) then \(\exists f : X\rightarrow U\) such that \((\forall x\in X) (x\in f(x)).)\) </p> |
The conclusion Form 163 \( \not \Rightarrow \) Form 68 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
