Progress on Gilbreath’s conjecture
14 hours ago
- Gilbreath's conjecture is simple to explain but challenging to prove, with Paul Erdős speculating it would take 200 years to prove.
- The conjecture is difficult because it lacks obvious mathematical tools, unlike well-studied problems such as differential equations.
- Terence Tao and coauthors published a paper analyzing a random model that mimics Gilbreath's calculation, offering heuristic plausibility but noting rigorous proof remains out of reach.
