Erdős Problem 323: I

Is it true that fk,k(x)ϵx1ϵf_{k,k}(x) \gg_\epsilon x^{1-\epsilon} for all ϵ>0\epsilon>0?

Mathematical statement

Is it true that fk,k(x)ϵx1ϵf_{k,k}(x) \gg_\epsilon x^{1-\epsilon} for all ϵ>0\epsilon>0?

This would have significant applications to Waring's problem. Erdős and Graham describe this as 'unattackable by the methods at our disposal'.

Statement artifacts, not proofs

These records expose exact Lean propositions and statement-only wrappers. Defining a proposition does not supply a proof of it. A placeholder-bearing target also contains no proof. Elaboration checks syntax and types; it does not certify that a formalization perfectly captures every nuance of the informal problem.
