In the four-plus-six spatial reference split, the base has four ordinary spatial dimensions and its perpendicular complement has six. Time is a separate coordinate in the infinite-dimensional physical spacetime. This four-plus-six split concerns ten spatial directions in the matter domain.

The normal bundle is made of ordinary spatial directions in one containing manifold. Its complex component ranks describe those directions and the field on them. This note adds consequences of the shared normal geometry; it does not select physical particles, calibrate electric response or derive an action. In the maintained four-dimensional spatial base/ten-domain construction, the complex normal rank is three. Comparisons below keep the same carrier prescription at other ranks.

1. The Charge Character Detects Its First Odd Order

Let WmW_m have complex rank mm, Dm=det⁡WmD_m=\det W_m, and

Em+=ΛevenWm⊗(1⊕Dm−1),Em−=ΛoddWm⊗(1⊕Dm−1). E_m^+=\Lambda^{\mathrm{even}}W_m\otimes(1\oplus D_m^{-1}),\qquad E_m^-=\Lambda^{\mathrm{odd}}W_m\otimes(1\oplus D_m^{-1}).

On degree rr the determinant-normalized generator has eigenvalues r/mr/m and r/m−1r/m-1, each with multiplicity (mr)\binom mr. Introduce an unnormalized character variable xx, so its powers are the integer weights r,r−mr,r-m. The binomial even-grade projection gives

Gm+(x)=1+x−m2[(1+x)m+(1−x)m]. G_m^+(x)=\frac{1+x^{-m}}2\big[(1+x)^m+(1-x)^m\big].

The complete character is Gm(x)=(1+x−m)(1+x)mG_m(x)=(1+x^{-m})(1+x)^m, invariant under

x⟼x−1.x\longmapsto x^{-1}.

For even mm, Gm+G_m^+ is also invariant. For odd mm,

Gm+(x)−Gm+(x−1)=(1+x−m)(1−x)m. G_m^+(x)-G_m^+(x^{-1})=(1+x^{-m})(1-x)^m.

Set x=et/mx=e^{t/m}. The right side starts as −2tm/mm-2t^m/m^m when mm is odd. The left side is twice the odd part of Tr⁡Em+etQ\operatorname{Tr}_{E_m^+}e^{tQ}. Therefore, for every positive odd mm,

Tr⁡Em+Qk=0(k<m, k odd),Tr⁡Em+Qm=−m!mm. \operatorname{Tr}_{E_m^+}Q^k=0\quad(k<m,\ k\text{ odd}),\qquad \operatorname{Tr}_{E_m^+}Q^m=-\frac{m!}{m^m}.

For even mm, every odd moment vanishes. In particular, among all m≥2m\ge2,

Tr⁡Em+Q3≠0  ⟺  m=3,Tr⁡E3+Q3=−29. \boxed{\operatorname{Tr}_{E_m^+}Q^3\ne0\iff m=3},\qquad \operatorname{Tr}_{E_3^+}Q^3=-\frac29.

This is an unbounded rank statement, not just a finite scan. At rank one a nonzero cubic also exists, but there is no nontrivial triplet carrier. The full Clifford completion cancels all odd moments, including the cubic. Its rank-three odd complement contributes +2/9+2/9. The signal concerns the specified even carrier or a parity-sensitive trace; it is not a physical anomaly coefficient.

Complex normal rank Real normal directions First nonzero odd moment of even carrier Cubic trace
2 4 None 0
3 6 Third, −2/9-2/9 −2/9-2/9
4 8 None 0
5 10 Fifth, −24/625-24/625 0
7 14 Seventh, −720/117649-720/117649 0

Requiring a nonzero cubic parity-sensitive fingerprint would select rank three within m≥2m\ge2. That is an additional physical or simplicity premise to justify, rather than a new measured property of particles.

2. The Same First Order Is The Normal Volume Polynomial

For independent rotation-plane weights aia_i, the full parity difference is

Tr⁡Em+etQa−Tr⁡Em−etQa=(1+e−t∑iai)∏i(1−etai). \operatorname{Tr}_{E_m^+}e^{tQ_a}-\operatorname{Tr}_{E_m^-}e^{tQ_a} =\left(1+e^{-t\sum_i a_i}\right)\prod_i(1-e^{ta_i}).

Its first nonzero coefficient is 2(−1)m∏iai2(-1)^m\prod_i a_i at degree mm. Let the actual skew rotation matrix on the ordinary normal space have blocks

A=⨁i=1m(0−aiai0). A=\bigoplus_{i=1}^m \begin{pmatrix}0&-a_i\\a_i&0\end{pmatrix}.

With this ordered real orientation, Pf⁡(A)=(−1)m∏iai\operatorname{Pf}(A)=(-1)^m\prod_i a_i. If Γ\Gamma is normal exterior parity, then

Tr⁡Em+⊕Em−(ΓQam)=2m!Pf⁡(A). \boxed{\operatorname{Tr}_{E_m^+\oplus E_m^-}(\Gamma Q_a^m) =2m!\operatorname{Pf}(A)}.

Thus the first parity-sensitive character order and the degree of the ordinary normal oriented-volume polynomial are the same mm. At six real normals both are cubic. The Pfaffian's degree and exterior-volume construction are standard mathematics; see Elkies's notes. The related Clifford supertrace/top-exterior-symbol machinery is explained in Getzler (1983), section 1, theorem 1.8. The character normalization and two-branch formula above are derived here for this carrier, not attributed to a physical mechanism in those references.

This is pointwise algebra. Replacing the variables by curvature two-forms gives a formal top characteristic polynomial of degree 2m2m in real form degree. For the rank-three normal bundle over a four-dimensional spatial base, a horizontal six-form vanishes. No nonzero characteristic number follows for that model. Nor does a cubic in rotation-matrix entries necessarily give a cubic in the underlying field.

3. Charge Weights As Relative Normal Rotation Alignment

Use Euclidean Clifford matrices γi\gamma_i on Λ∗Wm\Lambda^*W_m. For a normalized chiral spinor ray ψ\psi, define the real skew endomorphism

(Jψ)ij=i⟨ψ,γiγjψ⟩(i≠j),(Jψ)ii=0. (J_\psi)_{ij}=i\langle\psi,\gamma_i\gamma_j\psi\rangle\quad(i\ne j), \qquad (J_\psi)_{ii}=0.

Choose the Clifford signs so the vacuum gives the reference complex structure

J0=⨁i(0−110).J_0=\bigoplus_i\begin{pmatrix}0&-1\\1&0\end{pmatrix}.

A pure spinor means that the complex normal vectors annihilating it under Clifford multiplication form an isotropic subspace of the maximum dimension mm. With the positive real metric this subspace and its conjugate determine an orthogonal complex structure. The bilinear JψJ_\psi above is that structure for a normalized pure spinor.

The plane-pair entries measure 1−2ni1-2n_i, with nin_i the corresponding occupation-number operator. Consequently

ℓψ=−Tr⁡(JψJ0)2m=1−2⟨N⟩ψm,⟨Qb⟩ψ=1−ℓψ2−b,b=0,1. \ell_\psi=-\frac{\operatorname{Tr}(J_\psi J_0)}{2m} =1-\frac{2\langle N\rangle_\psi}{m},\qquad \langle Q_b\rangle_\psi=\frac{1-\ell_\psi}{2}-b,\quad b=0,1.

When Jψ2=−IJ_\psi^2=-I, this is a relative alignment of two actual orthogonal rotation structures on the normal spatial directions. The last identity still holds for a nonpure spinor whose JψJ_\psi fails that condition, but then it is only a bilinear alignment quantity.

At m=3m=3, every positive-chiral spinor is pure and yields an orthogonal complex structure. To see the exceptional simplification, write it as a+αa+\alpha with

α∈Λ2W3.\alpha\in\Lambda^2W_3.

Every such two-form is decomposable. If a≠0a\ne0, then

aexp⁡(α/a)=a+α,a\exp(\alpha/a)=a+\alpha,

because α∧α=0\alpha\wedge\alpha=0. This is the usual pure-spinor graph. If a=0a=0, a decomposable two-form is pure as well. A definite even grade is either zero or two; the latter reverses two normal rotation planes relative to J0J_0. The central circle fixes the spinor ray, so its associated JψJ_\psi commutes with J0J_0. The charge table therefore has the geometric reading

Even grade Rotation alignment ℓ\ell Branch b=0b=0 Branch b=1b=1 Multiplicity
0 1 0 −1-1 1
2 −1/3-1/3 2/32/3 −1/3-1/3 3

Multiplicity counts components in the representation, not a finite number of allowed spatial headings. The determinant branch remains necessary: the same normal JψJ_\psi appears in two branches with charges differing by one.

Rank two also has pure even spinors, but both exterior grades are singlets and there is no triplet. At rank four, the fixed-grade state

ψ=e1∧e2+e3∧e42\psi=\frac{e_1\wedge e_2+e_3\wedge e_4}{\sqrt2}

has charge 1/21/2 in the unshifted branch and Jψ=0J_\psi=0. Its two-form is not decomposable. The same counterexample embeds at every m≥4m\ge4, retaining zero rotation on its first eight real directions. Therefore rank three is the largest rank where every chiral polarization automatically gives a full orthogonal normal rotation, and it also provides the triplet. This is compatible with, and mathematically related to, the earlier six-normal frame criterion; it is not statistically independent evidence.

Definite grade remains a selection premise. For example the normalized

ψ=1+e1∧e22\psi=\frac{1+e_1\wedge e_2}{\sqrt2}

at rank three gives ℓ=1/3\ell=1/3, unshifted charge expectation 1/31/3, and still a full orthogonal JψJ_\psi. This is a mixture of the existing charge eigenstates, not a new eigenvalue. Geometry alone has not selected the particle states, and depth three versus depth four remains unresolved by this local alignment.

4. A Matching Dimension Of Normal Orientation Geometry

With a fixed real orientation, all orthogonal complex structures on the ordinary 2m2m-normal space form SO(2m)/U(m)SO(2m)/U(m). Its real dimension is

dim⁡SO(2m)−dim⁡U(m)=m(2m−1)−m2=m(m−1). \dim SO(2m)-\dim U(m)=m(2m-1)-m^2=m(m-1).

For positive mm, this equals the number of normal spatial directions exactly when m(m−1)=2mm(m-1)=2m, hence m=3m=3. At rank three the orbit is

SO(6)/U(3)≅CP3.SO(6)/U(3)\cong\mathbb{CP}^3.

This follows from Spin⁡(6)=SU(4)\operatorname{Spin}(6)=SU(4) and the projective stabilizer S(U(1)×U(3))S(U(1)\times U(3)) of a ray in the four-component chiral module. The same six-dimensional projective geometry appears as the proposed spatial electron topology, but those two uses are not automatically the same object. A physical identification would need a normal-orientation Gauss map from an already spatial Q6Q_6 with rank-six differential, a compatible metric and the complete sector embedding. The earlier intermediate-depth obstruction still applies to the standard CP2⊂CP3\mathbb{CP}^2\subset\mathbb{CP}^3 inclusion. This dimension match is therefore a precise geometric lead, not a replacement of ordinary spatial directions by coefficient-space coordinates.

5. Aggregate Frame Power Does Not Determine Oriented Volume

Retain every base-spin index of the bilinear frame qAB=β(xA,yB)q_{AB}=\beta(x_A,y_B) in the complexified normal space. Its positive real form gives

Q=∑A,B∥qAB∥2,Ω=2Im⁡∑A,BqABqAB†. Q=\sum_{A,B}\|q_{AB}\|^2,\qquad \Omega=2\operatorname{Im}\sum_{A,B}q_{AB}q_{AB}^\dagger.

This is covariant under real normal rotations and invariant under unitary changes of the retained base-spin frames and the common phase of the tensor. A single nonzero null q=u+ivq=u+iv gives one real plane, with

Ωq=2(vuT−uvT).\Omega_q=2(vu^T-uv^T).

Its sole positive skew singular value is ∥q∥2\|q\|^2. An aggregate can retain several planes or cancel their circulations while keeping positive QQ.

Let e0,e1,e2,e3e_0,e_1,e_2,e_3 be the unit vacuum/triplet basis of F3F_3, with the second branch carrying D−1D^{-1}. The exact map uses v=A×Bv=A\times B,

ξ=aB−bA.\xi=aB-bA.

The following pointwise controls all keep the same map and metric:

Branch columns X;YX;Y Q/(N0N1)Q/(N_0N_1) Rank of Ω\Omega Pf⁡(Ω)\operatorname{Pf}(\Omega)
(e0);(e1)(e_0);(e_1) 1 2 0
(e0,e1);(e0,e2)(e_0,e_1);(e_0,e_2) 3/43/4 6 −1-1
(e0,e1);(e2,e3)(e_0,e_1);(e_2,e_3) 1 0 0
(e0,e1);(e0+e2,e1+e3)(e_0,e_1);(e_0+e_2,e_1+e_3) 3/43/4 2 0

The second example has Ω2=−I6\Omega^2=-I_6. The last has exactly the same normalized frame power but no full normal rotation. Rescaling its YY by 1/21/\sqrt2 also matches both intensities and the unnormalized frame power of the second example, without changing the rotation rank or Pfaffian zero. These are tensor preparations, not maintained single-charge particle states or spatial solutions.

There is an amplitude-independent bounded diagnostic. If the three positive skew singular values of Ω\Omega are sis_i, the nuclear-norm triangle inequality gives ∑isi≤Q\sum_i s_i\le Q. Hence

∣Pf⁡(Ω)∣=s1s2s3≤(Q/3)3,η=27∣Pf⁡(Ω)∣Q3∈[0,1],Q>0. |\operatorname{Pf}(\Omega)|=s_1s_2s_3\le(Q/3)^3,\qquad \boxed{\eta=\frac{27|\operatorname{Pf}(\Omega)|}{Q^3}\in[0,1]},\quad Q>0.

The complete three-plane example attains η=1\eta=1; the other examples give zero. The general 2m2m-normal version is mm∣Pf⁡(Ω)∣/Qm≤1m^m|\operatorname{Pf}(\Omega)|/Q^m\le1. Thus the diagnostic itself does not uniquely select three planes. A same-field action could distinguish complete orientation from scalar frame power, but it must supply that role. Because qq is bilinear in field components,

deg⁡ΨΩ=4,deg⁡ΨPf⁡(Ω)=12(m=3).\deg_\Psi\Omega=4,\qquad \deg_\Psi\operatorname{Pf}(\Omega)=12\quad(m=3).

This Pfaffian is not the earlier third-order normal tensor or its sixth-order invariant density. The quantities share normal-volume algebra while retaining their different field orders, spin contractions and physical premises.

6. Contribution And Verification

The concrete contribution is a shared geometric reading: the rank-three carrier's first charge asymmetry is cubic; the same normal dimension has a cubic oriented volume polynomial; and its complete chiral polarizations give rotation structures whose definite-grade alignment reproduces the existing charge weights. Higher rank controls fail the universal polarization-to-rotation property. This supplies further conditional structure for investigating the four/six/ten geometry. It does not favor four physical particle-sector assignments or settle electric charge, neutral-state occupation, physical handedness or antiparticles.

The single exact checker and results use rational arithmetic and finite Gaussian-integer Clifford preparations. They compare ranks one through sixteen, independently check character values, verify multivariate leading terms, rotation/reflection covariance of the Pfaffian, and the correlated-frame and charge-alignment controls. The character theorem and embedded higher-rank counterexample extend the relevant conclusions beyond the finite comparison. No particle simulation is used.

Complete Polarization Metric and Central Transport

The ray-metric result proves that this same pure chiral map has exactly sixteen times the unit-vector Fubini–Study metric in the ordinary normal Frobenius norm. Rank three covers the complete chiral projective space, while rank four loses two tangent directions unless purity is separately imposed. The canonical normal connection derives its actual Spin vacuum line and determinant trace relation, retaining the half-determinant shift rather than identifying exterior weights with physical Spin transport. These results do not select observed electric charge.
