PRH | Educ | 6.6 • Blur Geometry (UG Version): Between Euclid and Lobachevsky

We introduce Blurrichevsky geometry, an observer-aware interpolation between Euclidean and hyperbolic geometry. A scale kernel first produces a blend parameter $\beta \in[0,1]$. Model A then uses the rotational metric $$g_\beta=d r^2+w_\beta(r)^2 d \theta^2, \quad w_\beta(r)=(1-\beta) r+\beta \frac{\sinh (\kappa r)}{\kappa},$$ whose curvature is ...

χ‑Spectral Topology of Hyperbolic Structure: Lobachevsky Geometry as a Topological Invariant of χ‑Reality

Abstract This article develops the χ‑spectral reinterpretation of hyperbolic geometry as a topological invariant of χ‑Reality. Classical Lobachevskian geometry, traditionally understood as a metric manifestation of constant negative curvature, is reconstructed as a projective signature induced by operator‑spectral segmentation of the χ‑vacuum S³.
