Calculation record
Causal local Dirac response and the limits of an instantaneous moment kernel.
The source probe, uniform background and projective geometry are stated
benchmarks. No measured particle interaction or physical vacuum is assigned.
Research context
- Causal limit of an instantaneous scalar moment interaction
Smooth spatially separated initial data show that the instantaneous scalar moment equation changes a local current before causal contact, so its physical use requires a controlled retarded reduction.
- Causal scalar response of the local Dirac equation
The written local scalar Dirac term has an exact retarded response about a specified uniform background, with two signed propagation channels, a conserved zero mode and a controlled static limit.
