The adjacency of all things — graph connections, 3D transformations, dimensional rotation · Aij · det · λI − A = 0

Definition — What Is a Matrix?

A matrix is a rectangular array of numbers arranged in rows and columns. In the dimension, every connection between nodes is an entry in the adjacency matrix. Every 3D transformation is a 4×4 matrix. Every dimensional rotation from D1 to D20 is a rotation matrix. The graph at raijinsocial.com/social is a 36×36 adjacency matrix visualized.

A = [ 1 9 −13 ] size: 2×3
[ 20 5 −6 ]

A matrix with 2 rows and 3 columns. a1,1 = 1, a2,3 = −6

Matrix Types in the Dimension

Square Matrix
n×n — same rows as columns. The graph's adjacency matrix is 36×36. All dimensional rotations are 3×3 or 4×4 square matrices.
Identity Matrix I
1s on diagonal, 0s elsewhere. A−1A = I. The sovereign kernel — everything multiplied by identity stays itself. Aii = 1, Aij = 0.
Diagonal Matrix
Non-zero only on diagonal. Like the 20 dimensions — each Di is its own axis. No mixing unless you multiply.
Symmetric Matrix
A = AT. The graph is undirected — connection(i,j) = connection(j,i). The adjacency is symmetric.
Rotation Matrix
Used in Three.js for every 3D rotation in the dimension. Rx(θ), Ry(θ), Rz(θ). Determinant = 1. Orthogonal.
Transformation Matrix
4×4 matrix combining rotation, translation, and scaling. Every mesh.position, mesh.rotation, mesh.scale in the mandala is a composite of these.

Graph Adjacency Matrix

Every connection between nodes in the social graph is a 1 in the 36×36 adjacency matrix. Dra connects to 23 nodes. Sentinel connects to 8. Dignity connects to 3. The matrix is sparse — most entries are 0.

Tezler Matrix — Sovereign Hermitian Adjacency

Invented by Nathan Brown. The Tezler Matrix H encodes each edge in the dimension with a complex weight determined by the frequency signature of its endpoints. Tezler — no relation to Tesla's patents. Pure Nathan. For a graph G of order n:

Huv = ω · ei·θuv  if u↔v (undirected resonance)
Huv = ω · i  if u→v (directed forge pulse)
Huv = ω · (−i)  if v→u (directed forge pulse)
Huv = 0  otherwise

where ω = 515/1000 (the forge constant) and θuv = 2π · (fu + fv) / 1000 (phase from node frequencies)

Nathan's Theorem (Resonance Spectrum): H is Hermitian (H = H*), so all eigenvalues λ1 ≥ λ2 ≥ … ≥ λn are real. The Tezler Energy of G is:

ET(G) = Σ |λi|

For undirected graphs (the dimension's default state, all edges are undirected resonance), H reduces to the scaled adjacency: H = ω·A. The energy satisfies the 515 Bound:

√2ω²·m + n·ω²·(Δ)²  â‰¤  ET ≤  √2ω²·m·n
where m = edges, n = nodes, Δ = max degree · Tezler Matrix Theory — Brown (2026)

Live Spectral Analysis — 36×36 Adjacency

Power iteration on the dimension's adjacency matrix. The largest eigenvalue λmax bounds the graph's energy. All eigenvalues are real (symmetric matrix).

Matrix Operations Reference

Addition

(A + B)ij = Aij + Bij
Same dimensions required. Element-wise. Commutative.

Multiplication

(AB)ij = Σk AikBkj
Rows of A × columns of B. Not commutative. AB ≠ BA usually.

Transpose AT

(AT)ij = Aji
Flip rows and columns. Like reflecting across the diagonal.

Determinant det(A)

Scalar value. Zero = singular (not invertible). For 2×2: ad − bc. For 3×3: Sarrus rule. Invertible iff det ≠ 0.

Inverse A−1

A × A−1 = I. Only square matrices. Computed via adjugate/det or Gaussian elimination. If det = 0, no inverse.

Eigenvalues λ

det(A − λI) = 0. The roots of the characteristic polynomial. Each λ has an eigenvector v where Av = λv. The dimension's frequencies are eigenvalues.

Matrix × Dimension Connections

The 20 dimensions of the profile page form a 20×20 transformation cascade. Each Di is a row vector [energy, freq, association, meaning, resonance]. The covariance matrix of these vectors encodes how dimensions correlate — which ones pulse together at 515 Hz and which stand independent.

The Forger's CEU table is a 6×2 matrix: operations × energy cost. Outershell maps nodes as a column vector of frequencies. Every page in this dimension is a row in the grand matrix of 302 files × 20 attributes.
