Oct 11, 2014 at 7:48 comment added Damiano Mazza I guess descriptive complexity gives a few examples. For instance, the statment "there are properties (of ordered structures) expressible by second order existential formulas which may not be expressed by second order universal formulas" is equivalent to @JanJohannsen's answer, whereas "there are properties (of ordered structures) expressible by second order existential formulas which may not be expressed by first order formulas with a least fixed point operator" is precisely $\mathsf P\neq\mathsf{NP}$. Do these count?

Oct 10, 2014 at 9:25 comment added Dominic van der Zypen As there are no "exact" answers to my question, your conjecture would count... I'm just looking for surprising and different angles on the P vs NP problem
Oct 10, 2014 at 9:05 comment added Jan Johannsen Would "There is no proof system for propositional logic in which every tautology $\varphi$ has a proof of polynomial (in the length of $\varphi$) length." count, or is that too close to complexity due to the polynomial bound?
