Censoring symmetry conjecture for Glauber dynamics on transitive graphs

About 18 years old · traced to

Let {Gn}\{G_n\} be a sequence of transitive graphs, and consider the Glauber dynamics for the Ising model on these graphs. Let βc\beta_c denote the critical temperature, let δ\delta satisfy ∣δ∣<βc|\delta|<\beta_c, and set

β1=βc−δ,β2=βc+δ.\beta_1=\beta_c-\delta,\qquad \beta_2=\beta_c+\delta.

A suitable notion of censoring is assumed for the censored dynamics. Censoring symmetry conjecture. There is cutoff for the original dynamics at β1\beta_1 if and only if there is cutoff for the censored dynamics at β2\beta_2.

This conjecture expresses the expected symmetry of Glauber dynamics around the critical temperature, extending the behavior observed for the mean-field Ising model to transitive graph sequences. The appropriate notion of censoring and the general validity of the equivalence remain open.
