Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.

- Authored annotation
- yields an irreducible character
Authored explanation
Over standard semisimple settings, irreducible representations have characters that organize decomposition and distinguish irreducible isomorphism classes under the stated hypotheses.
How to interpret this relation type
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

- one-particle symmetry representation
Authored explanation
Stable elementary particle species are classified by irreducible unitary representations of spacetime symmetry together with internal quantum numbers.
How to interpret this relation type
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.
