Calculation record
Checks supporting the boost and homogeneity classification theorem.
The theorem itself is analytic. These calculations check the representation,
the exact null-current cusp and the retained-frame escape from its hypotheses.
Research context
- A constraint on smooth homogeneous spinor interactions
Boost invariance and degree-two homogeneity force a potential that is differentiable on all nonzero spinor fields to be quadratic, precisely delimiting the role of the retained frame and null-current domain.
