摘要

我们对Bolthausen关于Sherrington-Kirkpatrick模型的复本对称公式的Morita型证明[E. Bolthausen, Stat. Mech. of Classical and Disordered Systems, pp. 63-93 (2018)]提供了一个简单推广,并证明了对于所有满足 β2Esech2(βqZ+h)1\beta^2 E \operatorname{sech}^2(\beta\sqrt{q}Z+h) \leq 1(β,h)(\beta,h),其中 q=Etanh2(βqZ+h)q = E\tanh^2(\beta\sqrt{q}Z+h),复本对称性成立。与[E. Bolthausen, Stat. Mech. of Classical and Disordered Systems, pp. 63-93 (2018)]相比,该论证的关键在于将条件二阶矩方法应用于适当约化的配分函数。
