The N-Gon Harmonization Programme: A Unified Framework for Cyclic-Symmetric Relative Equilibria (Papers I–IV)

Year: 2026
Type: preprint
Abstract: This deposit contains the complete four-paper submission package for the N-Gon Harmonization Programme: a unified analytical framework for the stability, bifurcations, and dynamics of regular polygon central configurations across the smooth Riesz family of homogeneous potentials V(r) ∝ r^(2−A), A ∈ (0, 2), with A = 2 the Kirchhoff–Routh vortex limit. The package consists of four papers (91 pages total) plus 10 Python validation scripts running 305+ numerical checks: Paper I (25 pp) — Closed-form vortex spectrum and asymptotic structure. Establishes the all-mode vortex master spectrum at A = 2, the sharp two-term Hampton asymptotic, and the universal A*(N)·N → 4 log 2 threshold across both parities (refuting a prior 4π²/(N log² N) conjecture for odd N). Paper II (33 pp) — Linear stability and bifurcation structure. The programme's headline result: an explicit linear isomorphism Φₙ intertwining the Maxwell two-ring perturbation space at μ = ρ = 1 with the regular 2n-gon perturbation space at every A ∈ (0, 2), yielding the structural identity A_bif(n) = A*_Nyq(2n) for every n ≥ 4. Paper III (16 pp) — Spatial structure and domain of validity. The Planarity Theorem: every smooth-Riesz relative equilibrium with positive masses under single-axis rotation is strictly planar, proved non-perturbatively via a maximum-z-body argument under V'(r) > 0. Perturbative consistency framework with J₂ oblateness, post-Newtonian corrections, and Kozai–Lidov. Paper IV (17 pp) — Programme synthesis. Hosts a Claim-Status Register classifying every headline result by proof status: analytically proved, reduced to standard identity, numerically validated conjecture, or heuristic/application-level. A single methodological backbone is used uniformly throughout: Fejér-kernel decomposition with Fourier-of-log-sin expansions and Gauss's digamma special-value formula, yielding closed forms in elementary special functions (harmonic numbers, digamma values, ζ(3)) suitable for symbolic and numerical verification. The 10 validation scripts (Python 3.10+, numpy/scipy/mpmath) reproduce every numerical claim in the papers. To run: cd validation && python3 .py.
