Shorter Refutation of Craig’s Interpolation and Derived Conjectures

Authors: Colin James III

We evaluate the formula for Craig’s interpolation as not tautologous. This means it is refuted, along with nine conjectures in the following cascade: proving Beth definability; verifying the division of larger problems into smaller problems; representing knowledge by suppression of information; proving intuitionistic and bi-intuitionistic logics, converse modality, tense logic, and extensions with path axioms; and ; and an orthogonality condition for defining duality between interpolates. These results form a non tautologous fragment of the universal logic VŁ4.
