The Standing and the Flowing: What Holds in Three Dimensions, What Flows in Four (INDYNA Research Note 48)

With the stored slab matrices of the three four-dimensional flag doubles (tesseract, 24-cell, 600-cell) we complete the linear dynamics of the model and record what it decides. (i) The dynamical self-observation of Note 46 is computed: condensed onto the 24 vertices of the observ...

Lattice Gauge Theory with the 600-Cell: Freezing, Shadow Superposition, and a Persistent Mass Gap (INDYNA Research Note 38)

The 120 icosians — the vertices of the 600-cell — form the largest finite subgroup of SU(2) and have been used as its lattice gauge group since Petcher and Weingarten. We reproduce the SU(2) behaviour of the plaquette with the 600-cell up to its freezing point, and show that supe...

The Stage of the Five: Self-Observation Among Four Counter-Poles, Holding by Exchange of Roles, and the Two Sides of the One Axis

Notes 39–45 fixed the gravitational side of the INDYNA model: a cascade down one axis to the narrowest point, corrected by the viscosity of the observer. This note fixes the structure of the other side, before any number is computed, so that the computations that follow are tests...

Theorems of the INDYNA Register, Part I: A Collection of the Exact Statements of Register Entries L381–L620 with Proofs

Research Notes 37–44 established a number of exact statements about the INDYNA model — the Regge geometry of the flag doubles of the regular polytopes, the observer as the tesseract, and the cascade of dual pairs. Several further statements were verified numerically in the regist...

Lattice Gauge Theory with the 600-Cell: Freezing, Shadow Superposition, and a Persistent Mass Gap (INDYNA Research Note 38)

The 120 icosians — the vertices of the 600-cell — form the largest finite subgroup of SU(2) and have been used as its lattice gauge group since Petcher and Weingarten. We reproduce the SU(2) behaviour of the plaquette with the 600-cell up to its freezing point, and show that supe...

The Hexagon Section: The Five 24-Cells as a 5×5 Matrix, the Observer Inside the Golden World, the Inclination of the Golden Decagon to the Rational Hexagon (cos α* = ρ), and the Twenty-Four Nodes on the Cut

Using the static Hessian H of the 600-cell flag double (2640 nodes) at its home, we compute what the fivefold stage of Note 46 looks like in numbers. (i) Reduced to the 120 vertices and decomposed into the five 24-cells, the breathing stiffness is a 5×5 matrix with a single diago...

Turning Inside Out Without Closing: The Eversion Spiral, Time as Scale, the Domino Cascade, the Field Equation and the Golden Ladder (INDYNA Research Note 40)

This note collects the exact results and the tests of register entries L464–L529, which prepared the gravitational candidate of Note 39 and the four-dimensional dynamics of Note 41. (1) In the model the Einstein coupling is a pure number, G_model = φ²/8π; the physical problem is...

The Viscosity of the Observer: A Candidate for Newton's Constant from the INDYNA Cascade and a Falsifiable Linewidth Prediction (INDYNA Research Note 39)

Within the INDYNA framework—Regge geometry on the regular polytopes of three and four dimensions, with the tesseract as observer—the gravitational scale follows from a cascade over all visible dual pairs of polytopes in 3D and 4D, starting from a spectral anchor of 0.50 meV. With...

One Angle Through the Dimensions: The 4D Tilt Angle is 30° Minus the 3D Counter-Rotation Angle; the Lack-of-Space Radius of the 600-Cell and the Openings of the Inverting Golden Pair

The INDYNA register derives the golden ratio twice from lack of space: in three dimensions from the counter-rotation of the two tetrahedra of the stella octangula, which halts at the icosahedron at the angle t* = arccos(φ²/√8) = 22.2388° (register L279), and in four dimensions fr...

The Viscosity of the Observer: A Candidate for Newton's Constant from the INDYNA Cascade and a Falsifiable Linewidth Prediction (INDYNA Research Note 39)

Within the INDYNA framework—Regge geometry on the regular polytopes of three and four dimensions, with the tesseract as observer—the gravitational scale follows from a cascade over all visible dual pairs of polytopes in 3D and 4D, starting from a spectral anchor of 0.50 meV. With...

The 600-Cell in the Millennium Problems: Poincaré's Dodecahedral Space, the Icosahedral Curve (BSD), and Hodge (INDYNA Research Note 37)

The objects of the INDYNA formula — the 120 icosians (the vertices of the 600-cell), E₈, the icosahedron and the field ℚ(√5) — appear exactly in several of the seven Millennium problems. We map where, and carry out the explicit computations that the register's objects allow: the...

The Riemann Hypothesis in the Geometry of the Golden Flag Double: Findings, Exact Reformulations, and the One Open Step (INDYNA Research Note 35)

This note does not prove the Riemann Hypothesis (RH). It records (i) exact identities that locate the objects of the INDYNA formula (M(g)=A₁+gA₂ over ℚ(√5), the icosahedral flag double, its 600-cell spinor layer and the E₈ anchor) inside the arithmetic of ζ; (ii) reformulations o...

Meeting Observers, the Two Golden Icosahedra of the Stella Octangula, and the Body-Diagonal Axis of the A7 Crystals (INDYNA Research Note 36)

In the INDYNA register an observer is a locked cube, the union T∪−T of the two tetrahedra of the stella octangula (L272). We compute exactly what observers share when they meet, in three and in four dimensions; we locate the icosahedron inside the pair of tetrahedra — not in eith...

The Riemann Hypothesis in the Geometry of the Golden Flag Double: Findings, Exact Reformulations, and the One Open Step (INDYNA Research Note 35)

This note does not prove the Riemann Hypothesis (RH). It records (i) exact identities that locate the objects of the INDYNA formula (M(g)=A₁+gA₂ over ℚ(√5), the icosahedral flag double, its 600-cell spinor layer and the E₈ anchor) inside the arithmetic of ζ; (ii) reformulations o...

The Anchor of the Cascade: Two Inseparable Halves, the Kink Rest Energy of CoNb2O6, and the Bounded Response of the Observer (INDYNA Research Note 43)

Note 39 derived a candidate for Newton's constant from a golden cascade anchored at 0.50 meV and corrected by the viscosity of the observer. Two of the open points of that derivation are addressed here. (i) Linewidth. For a real symmetric pencil a non-real eigenvalue carries exac...

Magnetism, Gravity and Inversion Breaking in Four Dimensions (INDYNA Research Note 42)

In the INDYNA vertex action the drift sector (spin 1, magnetism) and the form sector (spin 2, gravitation) of a radius field couple statically only through a lock-in deformation. In three dimensions the cube lock-in xyz provides this coupling. We prove that in four dimensions eve...

The Four-Dimensional Home and the Three Tesseracts (INDYNA Research Note 41)

We carry the INDYNA vertex action from three to four dimensions without changing it. On the flag doubles of the tesseract, the 24-cell and the 600-cell the area-weighted, spatially shadowed Regge action has a home (a stationary radius field) in all three bodies, and, as in 3D, th...

Galois Conjugation in Q(sqrt(5)) and Acoustic Phonon Scaling in Magnetically Ordered Icosahedral Quasicrystals

The two three-dimensional irreducible representations of the icosahedral group are Galois conjugates over Q(√5); in the cut-and-project description of icosahedral quasicrystals they are carried by physical space E∥ (phonons) and perpendicular space E⊥ (phasons). We point out a sh...

The Specific-Heat Test of the Icosahedral Cluster Magnon Spectrum: Predictions Stated in Advance for i-Au–Ga–Gd and i-Au–In–Eu, with Their Limits (INDYNA Companion Note)

This note places on record, before any comparison with data, the magnetic specific heat implied by the icosahedral cluster magnon spectrum, so that a later comparison with the published low-temperature specific heat of the ferromagnetic quasicrystal i-Au65Ga20Gd15 (TC=23 K) and t...
