2Authored explanation

Holley and Stroock develop functional inequalities and perturbation methods for stochastic Ising models. Martinelli's Saint-Flour lectures give a broad account of reversible Glauber dynamics, finite-volume spectral gaps, and temperature regimes. Lubetzky and Sly study heat-bath Glauber dynamics on square tori throughout the strong-spatial-mixing regime and relate finite-torus gaps to the infinite-volume gap.

These sources support the chain convention and the use of Poincare comparison. They do not tabulate the second eigenvalue for \(C_6\mathbin{\square}C_6\) at \(\beta=(\log2)/2\). Targeted searches for the exact size, the five rational conditional probabilities, and a finite-volume characteristic polynomial also found no such certificate. This is a status audit rather than a proof of novelty.

A full resolution needs a decomposition of the transition operator under spin flip and the automorphism group of the torus, followed by an exact characteristic polynomial or rational eigenvalue enclosures for every block. The present one-dimensional Ritz calculation covers one invariant trial subspace and supplies the upper endpoint recorded here.
