摘要
A multivariate generalization of mutual 資訊, multi-資訊, is defined in the 熱力學 limit. The definition takes phase coexistence into account by taking the infimum over the translation-invariant Gibbs measures of an interaction potential. It is shown that this infimum is attained in a pure state. An explicit formula can be found for the Ising square lattice, where the quantity is proved to be maximized at the phase-transition point. By this, phase coexistence is linked to high model complexity in a rigorous way.
