Abstract: For more than half a century, iterated Pearson correlation has been used in clustering, seriation, and information visualization despite the absence of a general analytical theory of its limiting dynamics. We completely resolve the fixed-point classification and relative Lyapunov stability problems for the correlation map in dimension three. An exact row-wise Gram factorization yields the identity $\operatorname{rank}C(A)=\operatorname{rank}(AH_n)$, forcing every fixed point to be singular and to lie on the relative boundary of the elliptope. In arbitrary dimension, we characterize all nondegenerate sign-valued fixed points and prove that their number is $2^{n-1}-1$.
For $n=3$, we derive an explicit coordinate representation and prove that the natural nondegenerate domain contains exactly seven fixed points: three rank-one patterned points, three rank-two mixed points, and one rank-two equicorrelation point, forming three orbits under the permutation action of $S_3$. Exact symbolic Jacobian calculations prove that the patterned points are locally asymptotically stable, whereas admissible invariant boundary curves realize the expanding multipliers and prove that the mixed and equicorrelation points are Lyapunov unstable relative to the natural nondegenerate domain.
Permutation equivariance maps the three patterned basins onto one another and implies equal Lebesgue measure whenever measurable. Reproducible basin computations classify every sampled admissible trajectory as converging to one of the three patterned attractors, with nearly equal frequencies and no trajectory-level classification mismatches under stricter validation. These results establish a complete fixed-point and relative Lyapunov stability theory in dimension three and provide strong reproducible evidence for the full-measure convergence conjecture for the union of the three patterned basins.
