Implications

This non-implication, Form 145 \( \not \Rightarrow \) Form 241, whose code is 6, 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: 9640, whose string of implications is:
    91 \(\Rightarrow\) 145
  • A proven non-implication whose code is 5. In this case, it's Code 3: 223, Form 91 \( \not \Rightarrow \) Form 241 whose summary information is:
    Hypothesis Statement
    Form 91 <p> \(PW\):  The power set of a well ordered set can be well ordered. </p>

    Conclusion Statement
    Form 241 <p> Every algebraic closure of \(\Bbb Q\) has a real closed subfield. </p>

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

The conclusion Form 145 \( \not \Rightarrow \) Form 241 then follows.

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

Name Statement
\(\cal N31\) L&auml;uchli's Model IV The set \(A\) is denumerable
