Mathematical Notation

Potential notation conflicts

In UHM theory, some symbols have multiple meanings depending on context:

  • DDDynamics dimension vs DdiffD_{\text{diff}}differentiation measure
  • H\mathcal{H} — Hilbert space vs HH — Hamiltonian vs HΓ\mathcal{H}_\Gamma — Hessian of free energy (in Freedom)
  • Φ\Phiintegration measure. For denoting arbitrary CPTP channels, Ψ\Psi is used
  • RRreflection measure vs R\mathcal{R} — regenerative term
  • C\mathcal{C} — primitive category (Axiom Ω⁷) vs CCconsciousness measure. The context space in the Exp category is denoted ΓE\Gamma_{-E}
  • γij\gamma_{ij} — elements of the coherence matrix vs γk\gamma_k — decoherence rates in the Lindblad dissipator (in different documents). Recommendation: use Γ2\Gamma_2 for decoherence rates (as in Theorem 8.1)

Context usually makes the meaning unambiguous.

Connection to IIT (Integrated Information Theory)

The integration measure Φ\Phi in UHM differs from Φ\Phi in Tononi's theory (IIT):

ParameterUHMIIT
DefinitionΦUHM=ijγij2/iγii2\Phi_{\text{UHM}} = \sum_{i \neq j} \lvert\gamma_{ij}\rvert^2 / \sum_i \gamma_{ii}^2ΦIIT\Phi_{\text{IIT}} = minimum mutual information over partitions
InterpretationCoherence between dimensionsIntegrated information
Computational complexityO(n2)O(n^2)NP-hard

UHM generalises IIT: the consciousness measure C=Φ×RC = \Phi \times R [T T-140] includes integration Φ\Phi and reflection RR. Differentiation DdiffDminD_{\text{diff}} \geq D_{\min} — a separate viability condition.

Evolution Equation

Full evolution equation with emergent internal time τ:

dΓ(τ)dτ=i[Heff,Γ]+D[Γ]+R[Γ,E]\frac{d\Gamma(\tau)}{d\tau} = -i[H_{\text{eff}}, \Gamma] + \mathcal{D}[\Gamma] + \mathcal{R}[\Gamma, E]

where:

Unitary term:

i[Heff,Γ]=i(HeffΓΓHeff)-i[H_{\text{eff}}, \Gamma] = -i(H_{\text{eff}}\Gamma - \Gamma H_{\text{eff}})

Here HeffH_{\text{eff}} is the effective Hamiltonian arising from the Page–Wootters constraint.

Dissipative term:

D[Γ]=kγk(LkΓLk12{LkLk,Γ})\mathcal{D}[\Gamma] = \sum_k \gamma_k \left( L_k \Gamma L_k^\dagger - \frac{1}{2}\{L_k^\dagger L_k, \Gamma\} \right)

Regenerative term [T]:

R[Γ,E]=κ(Γ)(ρΓ)gV(P)\mathcal{R}[\Gamma, E] = \kappa(\Gamma) \cdot (\rho_* - \Gamma) \cdot g_V(P)

where:

  • κ(Γ)0\kappa(\Gamma) \geq 0 — regeneration rate [T] (adjunction DΩR\mathcal{D}_\Omega \dashv \mathcal{R})
  • ρ=φ(Γ)\rho_* = \varphi(\Gamma) — categorical self-model of the current state [T] (φ-operator)
  • (ρΓ)(\rho_* - \Gamma) — unique CPTP relaxation [T]
  • gV(P)=clamp ⁣(PPcritPoptPcrit)g_V(P) = \mathrm{clamp}\!\bigl(\frac{P - P_{\mathrm{crit}}}{P_{\mathrm{opt}} - P_{\mathrm{crit}}}\bigr) — V-preservation gate [T] (Landauer + V-invariance, derivation)

Grothendieck Topology

See Grothendieck topology and Categorical formalism.

Bures metric (canonical form):

dB(Γ1,Γ2)=arccos(TrΓ1Γ2Γ1)=arccos(F)d_B(\Gamma_1, \Gamma_2) = \arccos\left(\mathrm{Tr}\sqrt{\sqrt{\Gamma_1}\Gamma_2\sqrt{\Gamma_1}}\right) = \arccos(\sqrt{F})

Fidelity:

Fid(Γ1,Γ2)=(TrΓ1Γ2Γ1)2\mathrm{Fid}(\Gamma_1, \Gamma_2) = \left(\mathrm{Tr}\sqrt{\sqrt{\Gamma_1}\Gamma_2\sqrt{\Gamma_1}}\right)^2
Notation Fid vs F

Fid\mathrm{Fid} is used for fidelity in contexts where FF could be confused with the experience functor F:DensityMatExpF: \mathbf{DensityMat} \to \mathbf{Exp}. In formulae where the context is unambiguous, the notation FF is permitted.

Two forms of the Bures metric

UHM uses both forms depending on context:

FormFormulaApplication
AngulardBangle=arccos(F)d_B^{angle} = \arccos(\sqrt{F})Geometric theorems (emergent time)
ChorddBchord=2(1F)d_B^{chord} = \sqrt{2(1-\sqrt{F})}Computations, ΔF, specification

Relation: dBchord=2(1cos(dBangle))2dBangled_B^{chord} = \sqrt{2(1 - \cos(d_B^{angle}))} \approx \sqrt{2} \cdot d_B^{angle} for small distances.

Bures ball:

BB(Γ,r)={ΣC:dB(Γ,Σ)<r}B_B(\Gamma, r) = \{\Sigma \in \mathcal{C} : d_B(\Gamma, \Sigma) < r\}

Bures covering: Family {Φi:ΓiΓ}iI\{\Phi_i: \Gamma_i \to \Gamma\}_{i \in I} covers Γ\Gamma if:

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

Site: Pair (C,JBures)(\mathcal{C}, J_{Bures}) where JBuresJ_{Bures} is the coverage function.

PFanoP_{\mathrm{Fano}}Fano predictive channel: PFano(Γ)=13pΠpΓΠpP_{\mathrm{Fano}}(\Gamma) = \tfrac{1}{3}\sum_p \Pi_p \Gamma \Pi_p — averaging over Fano lines
Πp\Pi_pProjector onto the 3-dimensional subspace of Fano line pp (p=1,,7p = 1, \ldots, 7)
α\alpha^*Optimal self-modelling parameter: α=argminF[Pα;Γ]\alpha^* = \operatorname{argmin} F[P_\alpha;\, \Gamma]
TeffT_{\mathrm{eff}}Effective Gap temperature: Teff=(Γ2/κ0)kBTphysT_{\mathrm{eff}} = (\Gamma_2 / \kappa_0) \cdot k_B \cdot T_{\mathrm{phys}}

r=κ/Γ2r = \kappa / \Gamma_2Dimensionless viability parameter — ratio of regeneration rate to decoherence rate
t=Teff/Tct = T_{\mathrm{eff}} / T_cDimensionless temperature — reduced to the critical value TcT_c

Spectral Geometry and Bimodular Construction

Symbols related to the bimodular construction of SM representations (T-178–T-181).

NotationMeaning
HFH_FFinite Hilbert space of the spectral triple as an (Aint,Aint)(A_{\text{int}}, A_{\text{int}}^\circ)-bimodule (KO-dim 6). Decomposition into irreducible bimodules reproduces one generation of SM fermions [T-178 [T]]
KO-dimKO-dimension =6= 6 (mod 8) — classification invariant of the real structure JJ; Connes's conditions: J2=1J^2 = 1, JD=DJJD = DJ, Jγ=γJJ\gamma = -\gamma J
DintD_{\text{int}}Dirac operator of the internal space; its eigenvalues determine the fermion mass ratios [T-180 [T]]
