Название: Cluster Expansion for d-Dimensional Lattice Systems and Finite-Volume Factorization Properties
Авторы: Olivieri E., Piceo P.
Аннотация:
We consider classical lattice systems with finite-range interactions in d dimensions. By means of a block-decimation procedure, we transform our original system into a polymer system whose activity is small provided a suitable factorization property of finite-volume partition functions holds. In this way we extend a result of Olivieri.
