What the Riemann hypothesis actually saysTo understand why this matters, it helps to know roughly what the Riemann hypothesis is about. The function equals zero at specific points, called its “zeros,” and each zero adds a layer of detail to how the primes are arranged along the number line. The Riemann hypothesis is a claim about where all of those zeros sit. Rather than attacking the whole hypothesis head-on, mathematicians have spent decades chipping away at smaller, related questions. Claude’s actual contributionThis is the number Claude moved.
