A new proof of the compactness theorem for propositional logic
The compactness theorem for propositional logic states that a demumerable set of propositional formulas is satisfiable if every finite subset is satisfiable. Though there are many different proofs, the underlying combinatorial basis of most of them seems to be Kόnig's lemma on infinite trees (see Smullyan [2], Thomson [3]). We base our proof on a different combinatorial lemma due to R. Rado [1]...
متن کاملProof of a Conjecture of a Pitts
Introduction In this paper we prove a conjecture of Andrew Pitts which states that the Beck Chevalley condition holds for lax pullbacks or comma squares of coherent toposes see Theorem below Pitts conjecture was put forward as a way towards the lax descent theorem for coherent toposes Theorem below The latter entails a dual version for pretoposes which was eventually established by Zawadowski i...
متن کاملA short proof of Harsanyi's purification theorem
A short and more general proof of Harsanyi’s puri...cation theorem is provided through an application of a powerful, yet intuitive, result from algebraic topology.
متن کاملA different short proof of Brook's theorem
Lovász gave a short proof of Brooks’ theorem by coloring greedily in a good order. We give a different short proof by reducing to the cubic case.
متن کاملA Short Proof of Zheludev's Theorem
We give a short proof of Zheludev's theorem that states the existence of precisely one eigenvalue in sufficiently distant spectral gaps of a Hill operator subject to certain short-range perturbations. As a by-product we simultaneously recover Rofe-Beketov's result about the finiteness of the number of eigenvalues in essential spectral gaps of the perturbed Hill operator. Our methods are operato...
