A statement that a physical quantity is constant under evolution or obeys a local continuity equation, often but not always associated with a symmetry.

This is an authored directed relation from the source endpoint to the target endpoint.
For continuous global action symmetries, Noether’s theorem yields a conserved current, subject to standard qualifications.
Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.

This is an authored directed relation from the source endpoint to the target endpoint.
A local conservation law is expressed by a continuity equation for a density and current.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
