Relaxed criteria of the Dobrushin-Shlosman mixing condition
Abstract
An interacting particle system (Glauber dynamics),
which evolves on a finite subset
in the integer lattice is considered.
It is known that
a mixing property of the Gibbs state in the sense of
Dobrushin and Shlosman ([DSh85]) is equivalent to
several very strong estimates in terms of the Glauber
dynamics ([SZ92b]).
We show that similar, but seemingly much milder
estimates are again equivalent to the Dobrushin-Shlosman
mixing condition, hence to the original ones in [SZ92b].
This may be understood as the absence of intermediate speed
of convergence to equilibrium.
