- The Navier–Stokes entry distinguishes an announced proof from a prize decision and labels a cited critique as a specific review, not a final ruling.
Field notes
The page combines a searchable problem index with concise explanations, field filters, and links to source material. Its Navier–Stokes notes separate the institute's announcement, a later critique preprint, and the stated rules for prize evaluation rather than treating them as one final verdict. The date labels identify some entries as verification updates, not newly published results.
