本文导出了一个一般判据,它保证了经典统计力学系统的状态在给定的关联函数系统中的唯一性。所述标准是 $$sumlimits_k {(m_{k + j}^A)} ^{ - 1/k} = infty$$ 对于所有j和所有有界集A,其中 $$m_k^A =(k!)^ { - 1} intlimits_A cdots intlimits_A {varrho _k }(x_1,ldots,x_k)dx_1 ldots dx_1 .$$
AbstractA general criterion is derived which assures the uniqueness of the state of a classical statistical mechanical system in terms of a given system of correlation functions. The criterion is $$sumlimits_k {(m_{k + j}^A )} ^{ - 1/k} = infty$$ for allj and all bounded setsA, where $$m_k^A = (k!)^{ - 1} intlimits_A cdots intlimits_A {varrho _k } (x_1 , ldots ,x_k )dx_1 ldots dx_1 .$$
