Implications

This non-implication, Form 128 \( \not \Rightarrow \) Form 375, 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: 1101, Form 128 \( \not \Rightarrow \) Form 155 whose summary information is:
    Hypothesis Statement
    Form 128 <p> <strong>Aczel's Realization Principle:</strong> On every infinite set there is a Hausdorff topology with an infinite set of non-isolated points. </p>

    Conclusion Statement
    Form 155  \(LC\): There are no non-trivial L&auml;uchli continua. (A <em>L&auml;uchli continuum</em> is a strongly connected continuum. <em>Continuum</em> \(\equiv\) compact, connected, Hausdorff space; and <em>strongly connected</em> \(\equiv\) every continuous real valued function is constant.) </p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 5922, whose string of implications is:
    375 \(\Rightarrow\) 78 \(\Rightarrow\) 155

The conclusion Form 128 \( \not \Rightarrow \) Form 375 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 \(A\)
