Domain-specific¶
- Lebesgue's lemma
- For a normed space X, subspace U and projection P onto U, the inequality norm(v-Pv) no greater than (1+norm P) times inf over u in U of norm(v-u) establishes quasi-optimality.
- … that the normed space, approximation subspace, bounded linear projection onto it, operator norm, target vector and best-approximation infimum are explicit and the stated inequality follows. to An applied instance preserves the same invariant under a changed scale, notation, jurisdiction, dataset, or implementation..
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.
