Elliott–Halberstam conjecture

The Elliott–Halberstam conjecture: for every θ<1\theta < 1 and A>0A > 0 there exists a constant C>0C > 0 such that 1qxθE(x;q)CxlogAx\sum_{1 \le q \le x^{\theta}} E(x; q) \le \frac{C x}{\log^A x} for all x>2x > 2.

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.
