modifiedGoldbach's conjecturecccbb1c49952
FieldFrom #2028To #2404
noteGrep finds no Goldbach conjecture statement in Mathlib (the only 'Goldbach' hit is the unrelated Fermat-numbers reference in NumberTheory/Fermat.lean).Grep finds no Goldbach conjecture statement in Mathlib; the only 'Goldbach' hit is the unrelated Fermat-numbers reference in NumberTheory/Fermat.lean line 98.
modifiedSchnirelmann's theorem (1930)44b30487b887
FieldFrom #2028To #2404
noteSchnirelmann density is defined in Combinatorics/Schnirelmann.lean (decl_exists confirmed), but the file's TODO explicitly lists 'Prove Schnirelmann's theorem' so the theorem itself is not yet formalized.Schnirelmann density is defined in Combinatorics/Schnirelmann.lean, but the theorem itself (bounded representation by primes) is not yet formalized.

modifiedPrime number theoremcd1f62412191
FieldFrom #2028To #2404
notedecl_exists confirms no `PrimeNumberTheorem` decl and no Mathlib/NumberTheory/LSeries/PrimeNumberTheorem.lean file; only prerequisites are present (Nat.primeCounting, Chebyshev bounds like Chebyshev.eventually_primeCounting_le, and zeta non-vanishing in LSeries/Nonvanishing.lean which explicitly calls itself a PNT prerequisite), so PNT itself is not yet formalized.Only PNT prerequisites (Nat.primeCounting, Chebyshev bounds, zeta non-vanishing) are present in Mathlib; the asymptotic π(n) ~ n/log n is not yet stated as a theorem.
