The positive-semidefinite matrix B describes spatial orientation gradients.
The underlying coordinates remain ordinary physical coordinates in
R10. Real field-component pairs are not additional dimensions.
Let L0>0 be a supplied length and choose one positive scalar function
m(C) of C=L02B. The action is
L=∫21⟨Jψ,∂tψ⟩dx−H,H=∫ρwdx,w=m(C)2+c2∣a∣2.
Its canonical equation is ψt=JδH/δψ and its complete
action and translation momentum are S=∫ρ and
Pi=−∫ρai. Write Mij=∂w/∂Bij,
bi=c2ai/w, qi=ρ(bi−2Mijaj) and Q=1−eeT.
The full functional derivative is
At a constant selected matrix with Dm=0, the exact equation reduces to
ψt=b⋅∇ψ+21(∇⋅b)ψ+(w−b⋅a)Jψ.
The tangent projector supplies the essential last subtraction. Let e0 be
a unit texture with a0=0, constant C=C∗, m(C∗)=ω and
Dm(C∗)=0. For any admissible smooth envelope f and constant physical
covector p, put wp=ω2+c2∣p∣2 and b=c2p/wp.
Then the complete spatial field
ψ(t,x)=eJ(p⋅x+wpt)f(x+bt)e0(x+bt)
solves this equation. Both the envelope and its internal texture translate.
The complete quantities satisfy
E=Swp,P=−Sp,v=−b,E2−c2∣P∣2=(Sω)2,P=Ev/c2.
The comoving clock is ω2/wp, and the rest inertia is
Sω/c2>0. The speed parameter c was inserted into the action;
these branch relations do not establish full Lorentz covariance or a
Lorentz-contracted profile. Fixing S=A gives the common integrated
Erest/ω=A without fitting a separate mass amplitude.
