Prime-Gap Dyadic Series: Perturbations, Exact Criteria and Certificates

Summary. A convergent dyadic series with nonnegative integer coefficients can be made rational by sparse nonnegative corrections of upper Banach density zero, eventually bounded by any f(n)→∞, while preserving every fixed modulus and, for a logarithmic allowance, short-block empirical distributions. For prime gaps the cumulative positions remain asymptotic to n log n; no primality conclusion is asserted. Summation by parts reduces the prime series to the gap series, and the tails TN=∑j≥1gN+j2−j satisfy TN+1=2TN−gN+1. That recurrence characterises rationality and yields finite tests with explicit remainder bounds. An exact finite certificate shows that a rational value of the prime series would have denominator at least 239998>1012040. The bound does not establish irrationality.

This paper covers the complete problem-specific reasoning surface for Erdős #251, including all registered result families and their boundaries.

It does not establish the validity of claims tagged Lean, which belongs to the cited kernel-checked source, or a solution to Erdős #251, which remains open.

Sparse congruence-preserving perturbations

At indices n,n+1, the pairs (0,6),(2,4),(4,2),(6,0) all have ordinary sum 6, while their dyadic contributions are 6,8,10,12 divided by 2n+2. If the cumulative correction before the pair is odd, we first add 1 at n−1. Choosing the pair then leaves the cumulative residue after the triple unchanged. We repeat this operation with nested moduli eventually divisible by every fixed integer.

Finite changes alone preserve rationality, so we use infinitely many triples. Making their separations tend to infinity gives upper Banach density zero, but also makes each weighted contribution smaller. We compensate by increasing the range of choices inside a pair. The estimate (5) shows that all later ranges together cover the gap between adjacent choices at the current stage. The set containing the supports and the interval of sums are chosen before the value to be attained.
