Implications

This non-implication, Form 80 \( \not \Rightarrow \) Form 179-epsilon, 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: 1179, whose string of implications is:
    60 \(\Rightarrow\) 10 \(\Rightarrow\) 80
  • A proven non-implication whose code is 3. In this case, it's Code 3: 993, Form 60 \( \not \Rightarrow \) Form 125 whose summary information is:
    Hypothesis Statement
    Form 60 <p> \(C(\infty,WO)\): Every set of non-empty, well orderable sets has a choice function.<br /> <a href="/books/2">Moore, G. [1982]</a>, p 125. </p>

    Conclusion Statement
    Form 125 <p> There does not exist an infinite, compact connected \(p\) space. (A \(p\) <em>space</em> is a \(T_2\) space in which the intersection of any well orderable family of open sets is open.) </p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 7604, whose string of implications is:
    179-epsilon \(\Rightarrow\) 144 \(\Rightarrow\) 125

The conclusion Form 80 \( \not \Rightarrow \) Form 179-epsilon then follows.

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

Name Statement
\(\cal N3\) Mostowski's Linearly Ordered Model \(A\) is countably infinite;\(\precsim\) is a dense linear ordering on \(A\) without first or lastelements (\((A,\precsim) \cong (\Bbb Q,\le)\)); \(\cal G\) is the group of allorder automorphisms on \((A,\precsim)\); and \(S\) is the set of all finitesubsets of \(A\)
