Non-degeneracy of conditional limits for multi-spin systems with uniform mark distribution
Non-degeneracy of conditional limits for multi-spin systems with uniform mark distribution
Let be a finite set, let be an edge potential, and let . For , let denote the relevant Gibbs measure conditioned on , and let be the set of non-degenerate Gibbs measures defined by the preceding construction.
Non-degeneracy conjecture. For every , given lies asymptotically in .
The conjecture proposes that conditional limits are always non-degenerate for multi-spin systems with a uniform mark distribution, extending the proved result for two-spin systems. The source presents this as an open question; the general case remains unresolved.
