Set Theory and Logic


Refutation of the Goldblatt-Thomason Theorem

Authors: Colin James III

From the introduction, we evaluate the terms forth and back as a duality. Neither is negation of the other, hence refuting the core basis of the Goldblatt-Thomason theorem. The question posed by it is further answered by the universal logic VŁ4 that expresses by modal axioms all first-order definable properties of a binary relation, due to equivalences of the respective quantifier and modal operator.
