Set Theory and Logic


Refutation of Comorphism of Sites

Authors: Colin James III

The complex equation evaluated is not tautologous, hence refuting the conjecture of comorphism of sites as a functor with a covering lifting property. What follows is that the following are also refuted: surjections, inclusions, localic morphisms, hyperconnected morphisms, and equivalences of toposes. This further relegates category theory of Grothendieck to a non tautologous fragment of the universal logic VŁ4.
