How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
Zero tangential trace H(curl) space
Definition
Let be open and set where the norm is that of The real H(curl) graph space on a polyhedron. This is the closure-defined zero-tangential subspace used on this page. Identifying this closure with the full kernel of a particular boundary trace map is not part of the definition.
Remarks
On a bounded Lipschitz polyhedron admitting a finite matching affine tetrahedral mesh, every member has zero weak tangential trace in the trace-quotient sense of Weak tangential trace on a Lipschitz polyhedron.

Dependency tree · two levels
10 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
