Dimensional Analysis in Finite Ring Continuum

The paper explores the provenance of the fundamental physical units in a physical universe defined over a finite holographic substrate: a finite totality whose capacity bounds the state count of every embedded observer. The holographic principle derives this bound as a constraint on continuum theories; here it is the substrate itself. The units are identified as the four horizons of the substrate: the Planck length, momentum, time, and energy, one per representation domain of the framed shell.

#DescriptionStatusSource
A. Inputs: imported, not derived here
A1p10001The framed substrate: the Subject shell $\Fp(\chron;0,1,\gen)$ with $\p=4\kap+1$, the derived quarter-turn $\It=-\gen^{\kap}$, the phase cycle $4\kap=2\pi=\p-1$, the framed-complex labels; the Carrier $\Car$ of cardinality $\Om=4\dS+1$ with its admissibility congruences; the realisation doctrine (a row stating what a physical term denotes, defended by its consequences and killed by its falsifier).I
A2p10002The holographic principle as the count: the capacity $\dS$ is the de Sitter entropy, the finite number of physical states behind the observer’s horizon, the one imported number of the paper.I
A3p10003The shell Fourier structure: on $\Fp^{\Phi}$, $\Phi=C_{\p-1}$, the matrix $W_{jk}=\gen^{jk}$, the normalized operator $F=\It W$ with $F^{2}=J$, $F^{4}=I$, and the fractional family with its cardinal skeleton $\{0,\kap,2\kap,3\kap\}$.I
[Akhtman 2026]; Rem. 4
A4p10004Classical dimensional analysis and the Planck units: the $\Pi$-theorem, the free-abelian exponent group of $M$-$L$-$T$, Planck’s construction of the natural units from $\{c,\hbar,G\}$, and the observation that only dimensionless ratios of constants are measurable.I
A5p10005The registrability hierarchy of the framework: coherent registration bounded at $\sqrt\p$, read on the exponent lattice as the coherence window $2\sqrt\kap=\sqrt{\p-1}$; the finite-field algebra of square classes and cyclic groups used throughout.I
A6p10006The Unruh and Hawking temperature forms, $T_U=\hbar a/2\pi c\,k_B$, as the shape the temperature domain closes on.I
B. The registers and the labels
B1p10007The Carrier: the finite complete totality, a timeless torsor of $\Om$ attribute-free points, its cardinality its only absolute characteristic, its reframings $x\mapsto ax+b$ automorphisms; the Subject: a bounded observer, an embedded prime shell of capacity $\kap$ with frame data $\Fp(\chron;0,1,\gen)$, $\p^{2}<\Om$; the two definitions together the paper’s reading of the holographic principle.D
Defs. 1, 2, Rem. 1
B2p10008The Object: an observed system registered relative to the Subject’s frame, every entry a Subject residue, $(\dt;\,q,k,v)$ — relative time, position, winding, rate.D
Def. 3
B3p10009Units as scale assignments: the additive meridian action $(\Fp,+)$ and the multiplicative phase action $\Fpx$ are unit-free coordinate actions, a physical unit a scale assignment to a frame chart of them, a measure a coordinate reading relative to the assigned scale; a physical-interface reading is a coefficient with the domain label it is read in, the two periods typing the label exponents; a change of scale assignment leaves $\card(\Fp)=\p$ and $\card(\Fpx)=\p-1$ untouched.D
Defs. 4, 5, Prop. 1
B4p10010The residue phase label $\gen^{k}$ with the cardinal packet $1,\gen^{\kap},\gen^{2\kap},\gen^{3\kap}$; the framed-complex label space $\mathcal C_\p=\Fp\times\Fp$ with its $\p$-to-one evaluation; $\It$ the finite shell quarter-turn label.D
Defs. 6, 7, Prop. 2
C. The modular domain algebra
C1p10011The two domain generators: $\unitL$ attached to the additive meridian chart, anchored on the unit $1$; $\unitT$ attached to the drive’s phase chart, anchored on the chronon step; the origins carry no units. The modular labels $U_{r,s}=\unitL^{r}\unitT^{s}$ on $\Dp=C_\p\times C_{\p-1}$, the homogeneous quantity algebra $\Ap=\bigoplus\Fp U_{r,s}$, the domain $\domp(Q)$ of a homogeneous quantity.D
Defs. 8, 9, 10, 11
C2p10012The modular unit-domain group and the grading: $\{U_{r,s}\}$ is a finite abelian group isomorphic to $\Dp$ under $U_{r,s}U_{r',s'}=U_{r+r',s+s'}$, and $\Ap$ is $\Dp$-graded, $\Ap^{(r,s)}\Ap^{(r',s')}\subseteq\Ap^{(r+r',s+s')}$.T

C3p10013Fibrewise addition and the neutral-domain criterion: a sum of homogeneous quantities is homogeneous exactly when its nonzero summands share a domain, the fibre components adding separately; a monomial $\prod Q_j^{k_j}$ has domain $\sum k_j(r_j,s_j)$ and is a neutral-domain invariant iff that sum is $(0,0)$ in $\Dp$.T

C4p10014Admissible reframings: the triples $(a,m,\eps)$ — translation of the spatial origin, dilation of the unit, re-presentation of the drive $\gen\mapsto\gen^{\eps}$, $\eps\in\Zp^{\times}$ — and the two actions they induce on labels.D
Def. 12
C5p10015Window covariance: on a bounded window $|r|,|s|\le H<2\kap$ in the flag-free sector the labels are covariant under every admissible reframing; the bound is sharp (the label $(0,\pi)$ is pushforward-invariant yet non-neutral); the naive character is ill-defined on the modular projection and the would-be temporal character fails composition ($5^{2}\equiv1$ in $\Z_{12}^{\times}$); on the realized lattice the invariant labels are exactly $\{0,2\kap\}$; the $\sigma$-twisted action is equivariant by full sweep on $\p=13$ and $229$; the flagged label $(0,0;1)$ moves under $\eps=-1$.T

D. The four domains and the unit flag
D1p10017Chart duality: $[f]=\unitT^{-1}$; $\delta_S:D\mapsto D^{-1}$ is an involution of the domain group whose orbit on the generators is the four-domain structure (space, momentum, time, energy); $\delta_C$ the second involution, carrying $\unitL\mapsto[p]$, $\unitT\mapsto\unitE$.T

D2p10018The internal flag: $\Dp$ contains exactly one subgroup of order four, $\langle\unitT^{\kap}\rangle$, entirely in the time-exponent factor; $\Iq:=\unitT^{\kap}$, $\Iq^{4}=1$, $\Iq^{2}=\unitT^{\pi}$; no flag of space ($\Z_\p$ has no element of order four); the two periods interfere, $(\unitL\unitT^{\kap})^{\p}=\Iq$, on three shells.T

D3p10019The lift: the flag records the quarter the chart duality forgets — on charts the cardinal skeleton acts as $s\bmod2$ ($F$ exchanges the conjugate charts, $J$ fixes them), on labels $s\mapsto\Iq^{s}$ is an isomorphism $\Z_4\to\langle\Iq\rangle$ whose quotient by $\{0,2\kap\}$ returns the chart action; on the Carrier $\hbar^{2}=-1$, $\hbar^{4}=1$, $\hbar^{2}\ne1$, the crossing quantum of order four, never two. Shells $(13,2)$, $(173,3)$; Carriers $233$, $2\,408\,561$.T

D4p10020The crossing degree: the full label $(r,s;j)$, $j\in\Z$ the signed number of register crossings, realized as $U_{r,\,s+j\kap}$ with the sector $j\bmod4$.D
Def. 14
D5p10021The unit flag: the Planck constants carry the flag, $[h]=\unithbar=\Iq$ — the anchoring of the action quantum to the order-four flag, the realisation content of the paper. Falsifier: one empirically closed expression that adds an observer count to a unitful measure without the conversion quantum (an energy to a frequency, a momentum to a wavenumber).R
Prop. 5, § 5
D6p10022The flagged readings over the counts: $\unitE=[h][f]=\Iq\unitT^{-1}$, $[p]=\unithbar[k]=\Iq\unitL^{-1}$, one quantity per pair, the flagged reading one capacity step above its count; $[S]=\unitE\unitT=\Iq$ and every phase count neutral, $\unitE\unitT\unithbar^{-1}=1$; the absolute unit is horizon-inaccessible (no monomial of a window $H\ll\kap$ expresses the flag) and becomes visible at $\kap\le H<2\kap$.T

D7p10023A unit of measure is a reciprocal relation between two count systems, counts of one frame per count of another; the unit flag is its domain form, the register crossing made algebraic; the Planck relation the unique interface introducing energy without a mass primitive.

E. The quartet and its Carrier instantiation
E1p10024The quartet: the primitive triple $\{\lP,\tPl,\hbar\}$ — the two anchored horizons, flag-free re-anchorings of the two primal charts, $[\lP]=\unitL$, $[\tPl]=\unitT$, and the crossing quantum — with the dual horizons their crossed images, $\pP=\hbar/\lP$, $\EP=\hbar/\tPl$; the four horizons occupy the four domains, flag positions $(0,0,1,1)$; the pairing constants $c=\lP/\tPl=\EP/\pP$, $\hbar=\lP\pP=\tPl\EP$, $|k_B|=\pP\tPl$, and $G$ the one datum not internal to the square. The fundamental units are the Carrier’s horizons. Falsifiers: a fifth algebraically independent relation within the quartet lattice; a measured variation of the dimensionless ratios of the constants.R
Def. 15, Rem. 8, Def. 16, § 6
E2p10025One crossing, one action, and pairing closure: $\lP\pP=\tPl\EP=\hbar$ (the two faces of $c$ and $\hbar$ differ by the single relation $\ell p=tE$); the cross-domain relations reduce to the two generators $c$, $\hbar$, the mixed products their monomials, $|k_B|=\hbar/c$ derived; the relation lattice over $\{\lP,\tPl,\hbar\}$ has rank two and $k_B$, $\lP\EP$ add nothing; $4-1=3$ free scales in bijection with $\{c,\hbar,G\}$, the classical arity derived.T

E6p10029The residue assignments: the unit face (the Planck chart, each horizon the unit of its domain; $c=1$, $\hbar=1$ its labels) and the residue face (the square-root horizon band, $\hbar^{2}=\Om-1$, $k_B^{2}=\Om-2$); the mass scale’s two typed faces, the monomial $m_P^{2}=\hbar c/G$ in $\{\pm k_B\}$ and the horizon declaration $m_P^{2}\,\hat=\,\Om$, never composed.D R
§ 6.1 (the residue assignments)
E7p10030The Carrier register is $\Om$-hard: no bounded observer resolves the constants’ residues; the selection of a member in each pair $\{x,-x\}$ is a resolved fact of the instantiated totality, knowable to no sub-capacity frame (the window ladder, G2); the absolute unit values are read at the totality and their unit-face magnitudes are their only registrable manifestation.Ω

E8p10031The two moves from the Subject’s reading to the Carrier’s: re-anchoring within the fibre (the unit and the chronon step traded for the substrate-fixed marks) and the register crossing (the flag); the two rows of the four-domain figure mix them differently.D

§ 9
Collecting the tags separates what a reader must grant from what is derived. Imported are the framed substrate and the realisation doctrine (A1), the holographic count (A2), the shell Fourier structure (A3), classical dimensional analysis and the Planck units (A4), the registrability bound (A5) and the Unruh form (A6). Declared are the Carrier and the Subject (B1), the Object (B2), units as scale assignments (B3), the phase and framed-complex labels (B4), the domain generators and the quantity algebra (C1), the admissible reframings (C4), the space-exponent refinement (the declared half of C6), the crossing degree (D4), the residue assignments (the declared half of E6) and the two moves (E8). Realised are four rows, each with its falsifier: the unit flag on the Planck constants (D5), the unit as a reciprocal relation (D7), the quartet as the Carrier’s horizons (E1) and the horizon declarations (the realised half of E6). Theorems are the twenty-two rows tagged T (with the forced half of C6): the domain algebra (C2, C3, C5, the forced half of C6), the four domains and the flag (D1D3, D6), the quartet’s identities and its congruences (E2E5, E9), mechanics and temperature (F2F4), recovery, the ladder and the examples (G1G3) and the four verification rows (V1V4); every one of them exact, the witnessed ones decided by the package on the named shells and Carriers. $\Om$-hard is the Carrier register itself: the absolute unit values and the member selection of each residue pair (E7). Open is one item, the electromagnetic domain (O1). The paper’s title claim — dimensional analysis as the finite shell-domain calculus with the unit flag — is C2 with D2, carried to the constants by E1, E2 and E4.
