Parity Barrier

A fundamental limitation of sieve methods in analytic number theory, systematically identified by mathematician Atle Selberg in the 1940s. Sieve methods are inherently unable to distinguish between integers with an odd versus an even number of prime factors, preventing sieve results from being sharpened to identify true primes.
