The Glauber dynamics is the quintessential example of a local Markov chain, and its convergence rate is of great interest due to its simplicity and wide applicability. Webstudy Glauber dynamics for families of finite graphs of bounded degree. We show that if the inverse spectral gap of the Glauber dynamics on the ball centered at ρstays bounded as the ball grows, then the correlation between the state of a vertex ρand the states of vertices at distance rfrom ρ, must decay exponentially in r.
