Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Local Lorentz-invariant QFT with the usual spectral and unitarity assumptions obeys CPT symmetry.

How to interpret this relation type

Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.
