The later proposal for every positive deviation
Statement
For every n ≥ 1 and δ > 0, the infimum of P(S < E S + δ) over independent nonnegative integrable variables with E Xᵢ ≤ 1 equals . This infimum is attained. Taking the infimum over n gives .
Assumptions
- Strict threshold, fixed positive finite n and positive δ.
- The optimization ranges over all admissible distributions.
Scope
Ling’s later Corollary 1.3 proposes the fully sharp formula; it is not part of the linked unit-slack Lean proof.
This source presents a theorem with a proposed proof. Its wording does not establish acceptance or independent mathematical review.
