. Let be the complete carrier translation covector, whose physical momentum is . Allow every finite-kinetic-energy scalar velocity and laboratory vector velocity . The two isotropic translation Grams are
These follow from the exact ordinary- integrals and , multiplied by . Orthogonal projection in the supporting kinetic norm gives
Every other admissible velocity adds half its squared orthogonal kinetic norm. This is the exact minimum over these velocities, with a cost of scalar recoil. It is not a minimum over carrier/frame/flow velocities, positions or all fields, and is not a boost-derived inertia.
For a physical antisymmetric rotation , radial and obey and . Thus pointwise. Intrinsic and orbital vector terms may each be nonzero and cancel. In material variables , the induced frame covector is essential, including at . These velocities preserve zero carrier angular momentum but cannot repair a nonzero one at fixed radial positions.
For a compact radial cutoff, define for and , with the vector derivative norm summed over its components. In the stated family , , the exact result is
Separate coefficients are needed; a common velocity coefficient is generally suboptimal. For nonzero this improves the scalar-core family. Existing phase restoration remains unchanged. A genuine frame rotation can separately cancel carrier angular covector , with and . Its extra energy is ; no additional vector/frame cross energy remains in laboratory velocities.
For the preceding whole-space common-phase endpoint, replace only
by
. Its convex minimization,
bounds and conditional threshold retain their form. The optimized cost
strictly decreases when the nonzero charge offset is fixed. Positive phase
edges and are still required for that endpoint. Compact high-core
compensation retains both symmetry branches. The amended
complete-support-recoil/report.md and independent 340-check review
establish these initial-jet results; they do not establish evolution or
new physical particle properties.
Density Concentration And A Convex-Envelope Bound
In the fixed radial family, vary only the entropy coefficient to , holding and the associated branch fixed.
