OpenAI reports independent largest prime factors of consecutive integers

For every fixed 0<a,b<1, the natural density of integers n with P⁺(n)≤nᵃ and P⁺(n+1)≤nᵇ is ρ(1/a)ρ(1/b), where P⁺ is the largest prime factor and ρ is the Dickman function.

Understanding the problem

Read the background

For every fixed 0<a,b<1, the natural density of integers n with P⁺(n)≤nᵃ and P⁺(n+1)≤nᵇ is ρ(1/a)ρ(1/b), where P⁺ is the largest prime factor and ρ is the Dickman function.

Why it matters

The reported natural-density result resolves the Erdős–Pomerance joint independence conjecture and implies that either ordering of the largest prime factors has density one half.

What counts as progress

Can the joint Dickman law be proved in ordinary natural density?
