Paper 4: Calogero-Moser Integrability Test

Conjectures & Open Questions

Universality Conjecture (Revised, March 2026)

For N ≥ 3 particles in d ≥ 1 spatial dimensions, interacting via a singular central potential: (1) the pairwise Poisson algebra has infinite GK dimension; (2) the cumulative dimension sequence d_N(n) depends only on N; (3) the sequence is independent of spatial dimension, potential type (within singular class), mass ratios, and charge configurations. For regular potentials (V polynomial in r), the algebra is finite-dimensional.

N=4 sequence [6,14,62,1260]

N=5 sequence [10,25,145]
N=4 with 1/r², 1/r³, log(r) → [6,14,62]

Quantum Universality Conjecture (April 2026)

For all singular potentials (1/rⁿ, n ≥ 1), the quantum Moyal bracket algebra is exactly one dimension larger than the classical Poisson bracket algebra at level 3: dquantum(3) = dclassical(3) + 1. The extra generator is negative semi-definite (Legendre P₃ angular structure, 1/r¹⁴ divergence at collision), and is NOT conserved. For polynomial potentials (rⁿ), there is no quantum correction at any level.

1/r: [3,6,17,117] vs classical 116
1/r²: [3,6,17,117] confirmed
1/r³: [3,6,17,117] confirmed
1/r⁴: [3,6,17,117] confirmed
r²: no quantum growth
r⁴: no quantum growth
N=4 quantum not yet tested
log(r) not tractable (non-algebraic)

Critical Locus Conjecture

The local rank of the Poisson algebra, viewed on the reduced configuration space (shape sphere for N=3), has its critical locus at exactly the fixed-point set of the S_N action. Rank drops occur only at symmetric configurations: Lagrange (S₃), Euler (Z₂), isosceles (Z₂).

99,000 grid points, 11 configs
No non-symmetric anomalies found
Cross-potential consistency
S₄ extension untested (N=4)

Cosmological Perspective (Speculative)

If the universality conjecture holds for general N, the S_N symmetric fixed point of the cosmic N-body problem corresponds to the homogeneous, isotropic universe. The critical locus conjecture predicts a rank drop at this point: an algebraic explanation for the dimensional reduction from ~3×10⁸⁰ degrees of freedom to the Friedmann equation's single scale factor a(t).

d=3 explicitly computed
Charge-sign invariant (EM too)
Only N=3,4 tested
GR not modeled

Falsifiable Predictions (Paper 3)

Three predictions that would falsify or strengthen the universality conjecture:

P1: N=5, d=1 → [10, 25, 145] confirmed through L2; L3 in progress (AWS r6i.8xlarge)
P2: N=4 with 1/r², 1/r³, log(r) → all confirmed [6, 14, 62] (Apr 1, 2026)
P3: d(4) for 1/r² → predict matches d(4) for 1/r (level-4 universality)
