Where all of this comes from

Laegna is a private mathematics made public. This page names its own documents and the classical work each concept stands next to — so that any claim here can be checked against something older and better tested.

Primary

The repositories

Traditional

Classical mathematics, physics and spirituality

Octahedral / HEALPix sphere mapping

Górski et al., equal-area sphere pixelisation

The ball's quilt is a same-family construction: equal solid angle per cell, hierarchical refinement.

Loop subdivision & geodesic polyhedra

Buckminster Fuller; Charles Loop

The refinement operator R and its commutation with projection.

Conformal & inversive geometry

Möbius, Steiner; r ↦ 1/r

Interior/exterior duality and the fixed membrane.

Projective compactification

Real projective line, Riemann sphere, ∞ as a point

Laegna's ∞ ≡ 2 is a compactification with an octave index attached.

Renormalisation group

Wilson, Kadanoff

Scale as a coordinate; behaviour that repeats across octaves.

Fuzzy sets & many-valued logic

Zadeh; Łukasiewicz; Belnap's four-valued logic

Belnap's four values are the nearest classical relative of I, E, O, A.

Non-standard analysis

Robinson; infinitesimals

The Z-regime: structure below the continuum.

Tao Te Ching / Zen circle (ensō)

Laozi; Zen calligraphic tradition

The lane as way; the whole drawn in one unclosed gesture.

Runic and northern cosmology

Elder Futhark; world-tree levels

Mark-making as structure; thresholds and levels as octaves.

Holographic principle

't Hooft, Susskind

Finite boundary addressing an interior — the quilt as hologram.

Interactive

One last look at the multi-scale field

The infinite circle, again — now as a reading instrument

Push the magnitude outward and you are in Y-space, where the classical references above about compactification and renormalisation apply. Push it inward and you are in Z-space, the territory of non-standard analysis and of the pre-continuum logic graph.
