Two links at one point: an illustrated companion to the construction

This companion explains the construction in the accompanying manuscript Topological singularities in the codimension-two stratum of noncollapsed Ricci limits. The central distinction is between the fixed manifold that records the topology of a punctured neighbourhood and the limiting link that determines a metric tangent. We follow this distinction through the shrinking caps, the two volume normalizations, the radial curvature estimates, and the smooth filling procedure. The pictures locate the geometric pieces; exact formulas explain why their curvature remains controlled and why their topology can disappear in a tangent while remaining visible in every punctured neighbourhood. Illustrated companion to Topological singularities in the codimension-two stratum of noncollapsed Ricci limits. The deposit contains the companion PDF and an archive of its editable LaTeX source, figures, and reproducible figure generators.
