Implications

This non-implication, Form 69 \( \not \Rightarrow \) Form 79, whose code is 4, is constructed around a proven non-implication as follows:

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 9602, whose string of implications is:
    14 \(\Rightarrow\) 69
  • A proven non-implication whose code is 3. In this case, it's Code 3: 155, Form 14 \( \not \Rightarrow \) Form 79 whose summary information is:
    Hypothesis Statement
    Form 14 <p> <strong>BPI:</strong> Every Boolean algebra has a prime ideal. </p>

    Conclusion Statement
    Form 79 <p> \({\Bbb R}\) can be well ordered.  <a href="/articles/hilbert-1900">Hilbert [1900]</a>, p 263. </p>

  • This non-implication was constructed without the use of this last code 2/1 implication

The conclusion Form 69 \( \not \Rightarrow \) Form 79 then follows.

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

Name Statement
\(\cal M1\) Cohen's original model Add a denumerable number of generic reals (subsets of \(\omega\)), \(a_1\), \(a_2\), \(\cdots\), along with the set \(b\) containing them
