Mechanisms¶
- Dual-Basis Transform
- Its honest limit is that the two representations obey a localization trade-off: sharpening an object in one basis necessarily spreads it in the dual, so no single representation answers every question at once.
This sourceProves an uncertainty trade-off in which concentration of a signal in one representation limits its possible concentration in a dual representation.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no 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.
