This research aims to explore the relationship between the E8 root system and golden ratio scaling in projections onto the Coxeter plane.
E8 root system analyzed in an 8D space and projected onto the Coxeter plane using Cartan matrix eigenvectors.
Scaling factors derived from eigenvalues of the Coxeter element, emphasizing the role of 30th roots of unity and Fourier transforms.
Investigation of distances in Voronoi cells within 3D cross-sections based on the golden ratio.
Golden ratio φ = 1.618 identified in scaling factors of root distances and Voronoi boundaries.
3D cross-sections reveal distance ratios of 0.618, 1.618, and 2.618 connected to projections.
Fourier transform of E8 roots peaked at frequencies aligned with φ-related wavevectors.
