摘要

我们证明了多物种 Sherrington-Kirkpatrick (MSK) 自旋玻璃模型中局部磁化的 Thouless-Anderson-Palmer (TAP) 方程。其中一个关键要素是基于 Dey 和 Wu（J Stat Phys 185(3):22, 2021）建立的浓度结果。对于一般的 MSK 模型，这些方程在高温下是成立的，不需要对方差轮廓矩阵（\mathbf {\Delta }^2\）进行正半有限假设。

Thouless–Anderson–Palmer Equations for the Multi-species Sherrington–Kirkpatrick Model

We prove the Thouless–Anderson–Palmer (TAP) equations for the local magnetization in the multi-species Sherrington–Kirkpatrick (MSK) spin glass model. One of the key ingredients is based on concentration results established in Dey and Wu (J Stat Phys 185(3):22, 2021). The equations hold at high temperature for general MSK model without positive semi-definite assumption on the variance profile matrix \(\mathbf {\Delta }^2\).
