Can a single sign turn three mathematical results into errors?

Can a single sign turn three mathematical results into errors?

In a collection of mathematical papers created with the help of artificial intelligence, researchers withdrew three manuscripts after finding a sign error. That error invalidated an argument as well as two results that depended on it.

The initial collection contained seven hundred and twenty-two manuscripts, but that did not mean there were seven hundred and twenty-two verified theorems. Some papers had formalized proofs; others still needed review.

The lesson is specific: generating proofs faster also requires tracking what depends on each step and looking for where things might go wrong.
