Primes

• Underspecification
  • In inverse problems and physics, recorded data is consistent with infinitely many internal-state distributions (Hadamard ill-posedness), and regularization picks one, often without disclosure.

    This sourceIntroduces well-posedness and its failure (ill-posedness), the source of the non-uniqueness underlying inverse problems with nontrivial null spaces. (No DOI; pre-1910 journal article — see https://www.scienceopen.com for catalog record.)

Domain-specific

• Well-posed problem
  • Local, global, weak, strong, and conditional well-posedness are different claims.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
