VibeMathed reports this item as partial. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.
Anari, Charikar and Ramakrishnan asked whether every fractional perfect matching admits a perfect matching that is $\alpha$-thin with respect to it, meaning it crosses every cut at most $\alpha$ times the fractional amount. Resolved up to polylogarithmic factors.
The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.
