Implications

This non-implication, Form 277 \( \not \Rightarrow \) Form 90, whose code is 4, is constructed around a proven non-implication as follows:

  • This non-implication was constructed without the use of this first code 2/1 implication.
  • A proven non-implication whose code is 3. In this case, it's Code 3: 942, Form 277 \( \not \Rightarrow \) Form 91 whose summary information is:
    Hypothesis Statement
    Form 277 <p> \(E(D,VII)\): Every non-well-orderable cardinal is decomposable. </p>

    Conclusion Statement
    Form 91 <p> \(PW\):  The power set of a well ordered set can be well ordered. </p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 9779, whose string of implications is:
    90 \(\Rightarrow\) 91

The conclusion Form 277 \( \not \Rightarrow \) Form 90 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
