Implications

This non-implication, Form 39 \( \not \Rightarrow \) Form 188, whose code is 6, is constructed around a proven non-implication as follows:
Note: This non-implication is actually a code 4, as this non-implication satisfies the transferability criterion. Click Transfer details for all the details)

  • This non-implication was constructed without the use of this first code 2/1 implication.
  • A proven non-implication whose code is 5. In this case, it's Code 3: 110, Form 39 \( \not \Rightarrow \) Form 106 whose summary information is:
    Hypothesis Statement
    Form 39 <p> \(C(\aleph_{1},\infty)\): Every set \(A\) of non-empty sets such that \(\vert A\vert = \aleph_{1}\) has a choice function. <a href="/books/2">Moore, G. [1982]</a>, p. 202. </p>

    Conclusion Statement
    Form 106 <p> <strong>Baire Category Theorem for Compact Hausdorff Spaces:</strong> Every compact Hausdorff space is Baire. <p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 9612, whose string of implications is:
    188 \(\Rightarrow\) 106

The conclusion Form 39 \( \not \Rightarrow \) Form 188 then follows.

Finally, the
List of models where hypothesis is true and the conclusion is false:
