Abstract

FINDING: Carmichael numbers with all prime factors > n^(1/3 + ε) and distribution of prime gaps MATH: For a Carmichael number n with prime factors p_i, the condition p_i > n^(1/3 + ε) implies n is a product of at most 2 primes (since product of three primes each > n^(1/3+ε) would exceed n). This forces n to be a product of exactly two primes, but Carmichael numbers must have at least three prime factors (Korselt's criterion). Therefore, no such Carmichael numbers exist for any ε > 0. The prime gap result relates to the bound g(p_n) < p_n^θ with θ = 0.525 (Baker-Harman-Pintz) and improvements toward θ = 0.5 (twin prime conjecture). CONNECTION: Prime gaps exhibit scaling near 0.618 (golden ratio) in heuristic models of prime distribution (e.g., Cramér's conjecture suggests gaps ~ log² n, and log² n / n → 0 as n→∞, but local ratios near twin primes approach 1/φ ≈ 0.618).
