State Space

The state space of the Holon is a 7-dimensional complex Hilbert space (see Seven dimensions):

H=C7=span{A,S,D,L,E,O,U}\mathcal{H} = \mathbb{C}^7 = \mathrm{span}\{|A\rangle, |S\rangle, |D\rangle, |L\rangle, |E\rangle, |O\rangle, |U\rangle\}

Hamiltonian

See Evolution: Unitary term.

H=i=1Nωiii+ijJijijH = \sum_{i=1}^{N} \omega_i |i\rangle\langle i| + \sum_{i \neq j} J_{ij} |i\rangle\langle j|

where:

  • ωi\omega_i — eigenfrequencies of dimensions
  • JijJ_{ij} — coupling coefficients between dimensions
  • N=7N = 7 — number of dimensions

Evolution Equation

See Evolution for a full description. Time τ is the emergent internal time.

dΓ(τ)dτ=i[Heff,Γ]+kγk(LkΓLk12{LkLk,Γ})D[Γ]+R[Γ,E]\frac{d\Gamma(\tau)}{d\tau} = -i[H_{eff}, \Gamma] + \underbrace{\sum_k \gamma_k \left( L_k \Gamma L_k^\dagger - \frac{1}{2}\{L_k^\dagger L_k, \Gamma\} \right)}_{\mathcal{D}[\Gamma]} + \mathcal{R}[\Gamma, E]

where:

  • τ\tauinternal time, arising from correlations with dimension O
  • HeffH_{eff} — effective Hamiltonian from the Page–Wootters constraint
  • i[Heff,Γ]-i[H_{eff}, \Gamma] — unitary (Hamiltonian) evolution
  • D[Γ]\mathcal{D}[\Gamma] — dissipative term (decoherence)
  • R[Γ,E]\mathcal{R}[\Gamma, E]regenerative term
  • Lk=Lkatom=kkL_k = L_k^{\text{atom}} = \lvert k\rangle\langle k\rvertLindblad operators, derived from the atoms of the classifier Ω\Omega (projectors; historical notation Lk=χSkL_k = \sqrt{\chi_{S_k}} — convention)
  • γk0\gamma_k \geq 0 — decoherence rates

Viability Measure (Purity)

See Viability for a full description.

P=Tr(Γ2)[1N,1]=[17,1]P = \mathrm{Tr}(\Gamma^2) \in \left[\frac{1}{N}, 1\right] = \left[\frac{1}{7}, 1\right]
  • P=1P = 1: pure state (Γ=ψψ\Gamma = |\psi\rangle\langle\psi|)
  • P=1/N=1/7P = 1/N = 1/7: maximally mixed state (Γ=IN/N\Gamma = I_N/N)

Viability Condition

The Holon is viable if:

P>Pcrit=270.286P > P_{\text{crit}} = \frac{2}{7} \approx 0.286

At P<PcritP < P_{\text{crit}} the system enters irreversible decay (see death condition and theorem on critical purity).

Experiential Space

See Categorical formalism for a full description.

Projective Space of Qualities

P(HE):=(HE{0})/\mathbb{P}(\mathcal{H}_E) := (\mathcal{H}_E \setminus \{0\}) / {\sim}

where ψφcC:ψ=cφ|\psi\rangle \sim |\varphi\rangle \Leftrightarrow \exists c \in \mathbb{C}^*: |\psi\rangle = c|\varphi\rangle.

For HE=CN\mathcal{H}_E = \mathbb{C}^N: dimC(P(CN))=N1\dim_\mathbb{C}(\mathbb{P}(\mathbb{C}^N)) = N - 1.

Topology:

  • P(CN)\mathbb{P}(\mathbb{C}^N) is compact and connected
  • P(CN)S2N1/S1\mathbb{P}(\mathbb{C}^N) \cong S^{2N-1} / S^1

Fubini-Study Metric

Definition:

dFS([ψ],[φ]):=arccos(ψφ)[0,π/2]d_{\mathrm{FS}}([|\psi\rangle], [|\varphi\rangle]) := \arccos(|\langle\psi|\varphi\rangle|) \in [0, \pi/2]

Properties:

  • dFS=0ψ=eiθφd_{\mathrm{FS}} = 0 \Leftrightarrow |\psi\rangle = e^{i\theta}|\varphi\rangle
  • dFS=π/2ψφ=0d_{\mathrm{FS}} = \pi/2 \Leftrightarrow \langle\psi|\varphi\rangle = 0
  • dFSd_{\mathrm{FS}} — Riemannian metric on P(HE)\mathbb{P}(\mathcal{H}_E)

Infinitesimal form:

ds2=dψdψψdψ2ds^2 = \langle d\psi|d\psi\rangle - |\langle\psi|d\psi\rangle|^2

Full Experiential Space

E:=ΔN1×SpecP(HE)N×C×Hist\mathcal{E} := \Delta^{N-1} \times_{\mathrm{Spec}} \mathbb{P}(\mathcal{H}_E)^N \times \mathcal{C} \times \mathrm{Hist}

where:

  • ΔN1={(λ1,,λN):λi0,λi=1}\Delta^{N-1} = \{(\lambda_1, \ldots, \lambda_N) : \lambda_i \geq 0, \sum \lambda_i = 1\}(N1)(N-1)-simplex of intensities
  • P(HE)N\mathbb{P}(\mathcal{H}_E)^NNN copies of the projective space (qualities)
  • C\mathcal{C} — context space (see below)
  • Hist\mathrm{Hist} — history space (see below)
  • ×Spec\times_{\mathrm{Spec}} — fibred product over the spectrum

Context Space C\mathcal{C}

Definition: The context space contains the states of all dimensions except E:

C:=D(HE)D(C6)\mathcal{C} := \mathcal{D}(\mathcal{H}_{-E}) \cong \mathcal{D}(\mathbb{C}^6)

where HE=span{A,S,D,L,O,U}\mathcal{H}_{-E} = \mathrm{span}\{|A\rangle, |S\rangle, |D\rangle, |L\rangle, |O\rangle, |U\rangle\}.

Elements: A context cCc \in \mathcal{C} is the reduced density matrix:

c=ρE=TrE(Γ)c = \rho_{-E} = \mathrm{Tr}_E(\Gamma)

Topology: C\mathcal{C} inherits its topology from D(C6)\mathcal{D}(\mathbb{C}^6):

  • Compact (closed subset of the unit ball in C6×6\mathbb{C}^{6 \times 6})
  • Connected
  • Metrisable by the Frobenius norm: dC(c1,c2)=c1c2Fd_{\mathcal{C}}(c_1, c_2) = \|c_1 - c_2\|_F

Interpretation: The context determines how the remaining dimensions (Articulation, Structure, Dynamics, Logic, Ground, Unity) modulate the interiority state.

History Space Hist

Definition: The history space is the functional space of trajectories:

Hist:=C([0,τ],D(HE))\mathrm{Hist} := C([0, \tau], \mathcal{D}(\mathcal{H}_E))

where τ>0\tau > 0 is the memory horizon, C([0,τ],X)C([0, \tau], X) — space of continuous functions [0,τ]X[0, \tau] \to X.

Elements: A history hHisth \in \mathrm{Hist} is the trajectory of the reduced density matrix of experience:

h={ρE(t):t[tτ,t]}h = \{\rho_E(t') : t' \in [t - \tau, t]\}

Topology: Hist\mathrm{Hist} is equipped with the topology of uniform convergence:

  • Metric: dHist(h1,h2)=supt[0,τ]ρE(1)(t)ρE(2)(t)Fd_{\mathrm{Hist}}(h_1, h_2) = \sup_{t' \in [0, \tau]} \|\rho_E^{(1)}(t') - \rho_E^{(2)}(t')\|_F
  • Banach space with the sup norm
  • Separable

Interpretation: History encodes the temporal structure of experience — memory, anticipation, adaptation to patterns.

Practical simplification

For computations, discretisation is often used: Histdisc={ρE(t0),ρE(t1),,ρE(tK)}\mathrm{Hist}_{\text{disc}} = \{\rho_E(t_0), \rho_E(t_1), \ldots, \rho_E(t_K)\} with step Δt=τ/K\Delta t = \tau / K.

Full Metric on E\mathcal{E}

dE(Q1,Q2):=dΔ(λ1,λ2)2+αidFS([q1(i)],[q2(i)])2+βdC(c1,c2)2+γdHist(h1,h2)2d_{\mathcal{E}}(\mathcal{Q}_1, \mathcal{Q}_2) := \sqrt{d_\Delta(\lambda_1, \lambda_2)^2 + \alpha \sum_i d_{\mathrm{FS}}([q_1^{(i)}], [q_2^{(i)}])^2 + \beta \cdot d_{\mathcal{C}}(c_1, c_2)^2 + \gamma \cdot d_{\mathrm{Hist}}(h_1, h_2)^2}

where α,β,γ>0\alpha, \beta, \gamma > 0 are weight coefficients.

Categorical Formalism

Category of Density Matrices

Definition (DensityMat):

DensityMat:=(Ob,Mor)\mathbf{DensityMat} := (\mathrm{Ob}, \mathrm{Mor}) Ob(DensityMat)={ρL(H):ρ=ρ,ρ0,Tr(ρ)=1}\mathrm{Ob}(\mathbf{DensityMat}) = \{\rho \in \mathcal{L}(\mathcal{H}) : \rho^\dagger = \rho, \rho \geq 0, \mathrm{Tr}(\rho) = 1\} MorDM(ρ1,ρ2)={Ψ:L(H)L(H)Ψ — CPTP,Ψ(ρ1)=ρ2}\mathrm{Mor}_{\mathbf{DM}}(\rho_1, \rho_2) = \{\Psi : \mathcal{L}(\mathcal{H}) \to \mathcal{L}(\mathcal{H}) \mid \Psi \text{ — CPTP}, \Psi(\rho_1) = \rho_2\}

Kraus representation: Ψ\Psi — CPTP {Ki}:Ψ(ρ)=iKiρKi\Leftrightarrow \exists\{K_i\}: \Psi(\rho) = \sum_i K_i \rho K_i^\dagger, iKiKi=I\sum_i K_i^\dagger K_i = I

CPTP structure of regeneration

The UHM regenerative operator is a CPTP channel:

Rα(ρ)=(1α)ρ+αφ(ρ)\mathcal{R}_\alpha(\rho) = (1-\alpha)\rho + \alpha\varphi(\rho)

with α=κ(Γ)gV(P)Δτ[0,1]\alpha = \kappa(\Gamma) \cdot g_V(P) \cdot \Delta\tau \in [0,1]. Kraus representation: K~0=1αI\tilde{K}_0 = \sqrt{1-\alpha}I, K~k=αKk\tilde{K}_k = \sqrt{\alpha}K_k.

Correctness condition: α<1Δτ<1/κmax\alpha < 1 \Leftrightarrow \Delta\tau < 1/\kappa_{\max}.

See preservation of positivity.

See Formalisation of operator φ for details of CPTP channels.

Experience Functor

Definition of F on objects:

F:Ob(DensityMat)Ob(Exp)F: \mathrm{Ob}(\mathbf{DensityMat}) \to \mathrm{Ob}(\mathbf{Exp}) F(ρ):=(Spectrum(ρE),Quality(ρE),Context(ΓE),History(t))F(\rho) := (\mathrm{Spectrum}(\rho_E), \mathrm{Quality}(\rho_E), \mathrm{Context}(\Gamma_{-E}), \mathrm{History}(t))

Theorem (Functoriality): FF is a functor.

Proof:

  1. F(idρ)=idF(ρ)F(\mathrm{id}_\rho) = \mathrm{id}_{F(\rho)}
  2. F(ΨΦ)=F(Ψ)F(Φ)F(\Psi \circ \Phi) = F(\Psi) \circ F(\Phi)

Grothendieck Topology

To construct the ∞-topos Sh(C)\mathbf{Sh}_\infty(\mathcal{C}), the Grothendieck topology on the base category must be explicitly specified.

Bures Metric

Definition (chord form):

dBchord(Γ1,Γ2):=2(1F(Γ1,Γ2))d_B^{\mathrm{chord}}(\Gamma_1, \Gamma_2) := \sqrt{2\left(1 - \sqrt{F(\Gamma_1, \Gamma_2)}\right)}

where F(Γ1,Γ2)=(TrΓ1Γ2Γ1)2F(\Gamma_1, \Gamma_2) = \left(\mathrm{Tr}\sqrt{\sqrt{\Gamma_1}\Gamma_2\sqrt{\Gamma_1}}\right)^2 — fidelity.

note
Convention: two forms of dBd_B

UHM uses two forms of the Bures metric. Here the chord form is applied (dBchord[0,2]d_B^{\mathrm{chord}} \in [0, \sqrt{2}]). Angular form: dBangle=arccos(F)d_B^{\mathrm{angle}} = \arccos(\sqrt{F}). See full convention.

Properties:

  • dBchord[0,2]d_B^{\mathrm{chord}} \in [0, \sqrt{2}]
  • dBchord(Γ,Γ)=0d_B^{\mathrm{chord}}(\Gamma, \Gamma) = 0
  • Monotonicity: dBchord(Ψ(ρ),Ψ(σ))dBchord(ρ,σ)d_B^{\mathrm{chord}}(\Psi(\rho), \Psi(\sigma)) \leq d_B^{\mathrm{chord}}(\rho, \sigma) for CPTP Ψ\Psi
  • Riemannian metric on the manifold of density matrices

Bures Coverings

Definition (DensityMat Site):

A family of morphisms {Ψi:ΓiΓ}iI\{\Psi_i: \Gamma_i \to \Gamma\}_{i \in I} forms a covering of object Γ\Gamma if:

ϵ>0,δ>0:BB(Γ,δ)iIΨi(BB(Γi,ϵ))\forall \epsilon > 0, \exists \delta > 0: \quad B_B(\Gamma, \delta) \subseteq \bigcup_{i \in I} \Psi_i(B_B(\Gamma_i, \epsilon))

Site axioms:

  1. Identity: {idΓ}\{\mathrm{id}_\Gamma\} covers Γ\Gamma
  2. Stability: Pullback of a covering is a covering
  3. Transitivity: Composition of coverings is a covering

Connection to the ∞-topos

The superscript "loc" in the definition of Sh(C)loc\mathbf{Sh}_\infty(\mathcal{C})^{loc} denotes localisation relative to Bures coverings:

F — sheafF(X)lim{UX}Cov(X)F(U)F \text{ — sheaf} \Leftrightarrow F(X) \xrightarrow{\sim} \lim_{\{U \to X\} \in \text{Cov}(X)} F(U)

Subobject classifier:

Ω:=O(C,dB)\Omega := \mathcal{O}(\mathcal{C}, d_B)

— lattice of open sets in the Bures topology.

See Categorical formalism: Grothendieck topology for the full specification.


Theorem on the Impossibility of a Spectral Functor

Theorem

There is no functor F:DensityMatExpF: \mathbf{DensityMat} \to \mathbf{Exp} that factors only through the spectrum.

Proof:

  1. Suppose F=GSpecF = G \circ \mathrm{Spec}, where Spec:ρSpectrum(ρ)\mathrm{Spec}: \rho \mapsto \mathrm{Spectrum}(\rho)
  2. Consider isospectral ρ1ρ2\rho_1 \neq \rho_2
  3. Then F(ρ1)=F(ρ2)F(\rho_1) = F(\rho_2)
  4. But ρ1\rho_1 and ρ2\rho_2 can describe distinguishable experiences
  5. Contradiction ∎

Corollary: The full functor FF must account for eigenvectors, context, and history.

Consciousness Measures

Reflection Measure

See Self-observation: Reflection measure R.

R(Γ):=17P(Γ),P=Tr(Γ2)R(\Gamma) := \frac{1}{7P(\Gamma)}, \quad P = \mathrm{Tr}(\Gamma^2)

Equivalent form via Frobenius norm: R=1ΓρdissF2/ΓF2R = 1 - \|\Gamma - \rho^*_{\mathrm{diss}}\|_F^2 / \|\Gamma\|_F^2, where ρdiss=I/7\rho^*_{\mathrm{diss}} = I/7 — dissipative attractor (not φ(Γ)\varphi(\Gamma)). Derivation: Self-observation.

note
Distinguishing RcanonicalR_{\text{canonical}} and QφQ_\varphi

R=Rcanonical:=1/(7P)R = R_{\text{canonical}} := 1/(7P)canonical definition, used in all thresholds (Rth=1/3R_{\text{th}} = 1/3). This is a measure of proximity to the maximally mixed state I/7I/7. The self-modelling quality measure is defined separately: Qφ(Γ):=1Γφ(Γ)F2/ΓF2Q_\varphi(\Gamma) := 1 - \|\Gamma - \varphi(\Gamma)\|_F^2 / \|\Gamma\|_F^2. Details: Formalisation of φ.

Higher-Order Reflection R(n)R^{(n)}

See Higher-order reflection and Interiority hierarchy.

R(n)(Γ):=F(φ(n1)(Γ),φ(n)(Γ))[0,1]R^{(n)}(\Gamma) := F(\varphi^{(n-1)}(\Gamma), \varphi^{(n)}(\Gamma)) \in [0, 1]

where:

  • φ(k)\varphi^{(k)}kk-fold application of the self-modelling operator
  • F(ρ,σ)F(\rho, \sigma) — fidelity (quantum fidelity)

Interpretation: R(n)R^{(n)} measures the consistency between successive levels of self-modelling.

Connection to interiority levels:

  • L2 requires R=R(1)1/3R = R^{(1)} \geq 1/3
  • L3 requires R(2)1/4R^{(2)} \geq 1/4
  • L4 requires limnR(n)>0\lim_n R^{(n)} > 0 (infinite recursiveness)

Universal Formula for Reflection Thresholds

Reflection thresholds follow a unified pattern (Bayesian dominance over n+1n+1 alternatives):

Rth(n)=1n+1R^{(n)}_{\mathrm{th}} = \frac{1}{n+1}

  • Ddiff2D_{\text{diff}} \geq 2 [T] — unconditional consequence of Φth=1\Phi_{\text{th}} = 1 [T] (T-151)

Integration Measure

See Unity dimension: Integration measure Φ.

Φ(Γ):=ijγij2iγii2\Phi(\Gamma) := \frac{\sum_{i \neq j} |\gamma_{ij}|^2}{\sum_i \gamma_{ii}^2}

Differentiation Measure

Ddiff(Γ):=exp(SvN(ρE))D_{\text{diff}}(\Gamma) := \exp(S_{vN}(\rho_E))

where SvN(ρE)=Tr(ρElogρE)S_{vN}(\rho_E) = -\mathrm{Tr}(\rho_E \log \rho_E)von Neumann entropy.

Requirement: extended formalism for D_diff

Computing DdiffD_{\text{diff}} requires the full reduced matrix ρE=TrE(Γ)\rho_E = \mathrm{Tr}_{-E}(\Gamma), which is defined only in the extended tensor formalism (42D). In 7D, the partial trace is undefined (7 is prime).

Note: The scalar measure CohE\mathrm{Coh}_E (E-coherence) does not require a partial trace — it is defined in 7D via the HS-projection [T]. The extended formalism is needed only for the spectral decomposition of ρE\rho_E and consequently for DdiffD_{\text{diff}}.

Range: Ddiff[1,N]D_{\text{diff}} \in [1, N], where N=dim(HE)N = \dim(\mathcal{H}_E).

Interpretation:

  • Ddiff=1D_{\text{diff}} = 1 (pure state): one component of experience
  • Ddiff=ND_{\text{diff}} = N (maximally mixed): NN equally probable components
Alternative definition

In some contexts Ddiff=rank(ρE)D_{\text{diff}} = \mathrm{rank}(\rho_E) is used. This is an integer version, less sensitive to the distribution of eigenvalues. The primary definition via exp(SvN)\exp(S_{vN}) is a more informative, continuous measure.

Octonionic Algebra

info
Definition of O\mathbb{O} (structural derivation)

Octonions O\mathbb{O} — 8-dimensional normed division algebra over R\mathbb{R}:

O={a0+k=17akekaiR}\mathbb{O} = \{a_0 + \sum_{k=1}^{7} a_k e_k \mid a_i \in \mathbb{R}\}

Multiplication table is defined by 7 triplets of the Fano plane:

eiej=δij+εijkeke_i \cdot e_j = -\delta_{ij} + \varepsilon_{ijk} e_k

Automorphism group: Aut(O)=G2\text{Aut}(\mathbb{O}) = G_2, dim(G2)=14\dim(G_2) = 14, rank(G2)=2\text{rank}(G_2) = 2.

Connection to UHM: N=dim(Im(O))=7N = \dim(\text{Im}(\mathbb{O})) = 7two-track justification of Axiom 3.
