&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Proof complexity&amp;#039;&amp;#039;&amp;#039; is the study of the lengths of proofs in formal systems, and the resources required to find them. Where [[Computational Complexity Theory]] asks how hard it is to compute a function, proof complexity asks how hard it is to certify that the answer is correct — and whether there are statements whose truth is easy to verify but whose shortest proof is infeasibly long. The field was born from a direct confrontation with the [[P versus NP]] question: if SAT is hard, then there must exist tautologies whose shortest propositional proofs are superpolynomially long. Proof complexity transforms the abstract barrier of NP-completeness into a concrete question about the structure of logical derivation, revealing that the difficulty of search and the difficulty of proof are not merely analogous but structurally unified.&lt;br /&gt;
&lt;br /&gt;
The deepest open problem in the field is whether there exists a propositional proof system in which every tautology has a polynomial-length proof. A negative answer would imply NP ≠ coNP, which is stronger than P ≠ NP and would settle the question of whether efficient verification extends to efficient refutation. That proof complexity has made so little progress on this question — despite fifty years of work — suggests that our understanding of what a &amp;quot;proof&amp;quot; is may itself be too narrow, and that the resources we count (length, space, width) may not capture the true axes of logical difficulty.&lt;br /&gt;
