Looking for reference on NP-Completeness of proofs of length n

Given a deductive system $\Lambda$, and some well-formed-formula S, one can ask the question "Is there a proof S in $\Lambda$ of length n?" If n is presented in base-1 and if all the axioms of $\...

Is there a known automatic proof of the independence of the continuum hypothesis?

In 2002, L.C. Paulson gave a mechanized proof of the consistency of the axiom of choice by formalizing $V=L$ and its consistency. We could ask whether there is a formalized proof of the independence ...

Formalization of Interval Newton methods in a proof assistant or theorem prover

I am undertaking the task of formalizing Interval Newton Methods in Isabelle. To the best of my knowledge this hasn't been formalized in other proof assistants or theorem provers. However, I want to ...

Theorem prover fails to find simple set theory proof?

I am trying to use an automated theorem prover (SNARK) to prove a theorem in first-order logic. Tarski claims in his "a work on mereology" that the goal is provable from assertions 1-3 but he does ...

Regaining decidability by adding axioms that model real world situation

It is known that first order logic is too general to be decidable. Adding axioms with special meaning (e.g. expressing notions such as necessity/obligation, provability, etc.) leads us to modal logics ...

Do problems have to be statable in $\Pi_1$ to use Levin's universal search to find short proofs if P=NP

In If P=NP, could we obtain proofs of Goldbach's Conjecture etc.? it talks about the hypothetical world where P=NP and using the proof of it to prove a problem/theorem assuming that it has a short ...
