Two recorded approximation-degree and critical-level profiles
Original figure from the retained vector PDF.

Reading the figure

The dyadic example uses degrees two, four and eight with levels sixty, eighteen and three. The odd example uses degrees three, nine and twenty-seven with levels one hundred forty-four, twenty-four and four. These are finite illustrative profiles.

Original figure caption

These examples were recomputed exactly; the all-length assertions are proved separately.

For increasing permitted \(h_1<\cdots<h_d\), put \(q_i=(p+1)h_i\) and \(N=p^d\). The approximation-field degrees are \(p,p^2,\ldots,p^d\), with

\[ n_j=p^{d-j}q_{d-j+1}. \]

For odd \(p\), require \(p\nmid h_i\). For \(p=2\), require all \(h_i\) odd and positive. The leading ambient level is \(n_1\); \(n_2,\ldots,n_d\) are the successive critical approximation levels.

Scope

Every amplified ambient approximation still has leading level \(n_1\). The declining values plotted here are critical levels, not new leading valuations for those ambient matrices.

Source and conversion record

This edition preserves all 47 lessons, the opening orientation and both route sections. Figures are rendered from retained vector PDFs. Descriptions and recorded-data tables are reading aids. No mathematical generator, TeX build, proof audit or Lean replay was run for this conversion.
