摘要：
米歇尔·塔拉格朗在将均场自旋玻璃理论转化为严谨数学学科中发挥了决定性作用。本章回顾了该发展的历程，从物理起源的Sherrington-Kirkpatrick（SK）模型开始，到TAP和Almeida-Thouless稳定性框架的出现，最终以巴黎西的副本对称破缺（RSB）假设及其分层序参量为终点。随后回顾了早期的严格里程碑，包括高温结果和稳定性恒等式，并描述了Guerra和Aizenman-Sims-Starr的工作如何通过插值和腔方法巩固理论。本叙述的核心事件是塔拉格朗2006年对SK模型以及广泛混合p-自旋模型的巴黎西公式的证明，以及他对巴黎西测度的后续分析。此外，还讨论了塔拉格朗后来的程序，包括在扩展的Ghirlanda-Guerra恒等式下构造纯态以及在最大重叠处构造原子，以及由此产生的结构结果，如Panchenko的超度量定理和巴黎西公式的扩展。在整个过程中，指出了许多作者的相关贡献如何融入同一长期计划中，涵盖概率、分析和数学物理领域。
英文摘要：
Michel Talagrand played a decisive role in the transformation of mean-field spin glass theory into a rigorous mathematical subject. This chapter offers a narrative account of that development. We begin with the physical origins of the Sherrington-Kirkpatrick (SK) model and the emergence of the TAP and Almeida-Thouless stability frameworks, culminating in Parisi's replica symmetry breaking (RSB) ansatz and its hierarchical order parameter. We then review early rigorous milestones, including high-temperature results and stability identities, and describe the consolidation of interpolation and cavity methods through the work of Guerra and of Aizenman-Sims-Starr. The central event in this narrative is Talagrand's 2006 proof of the Parisi formula for the SK model and for a broad class of mixed $p$-spin models, and his subsequent analysis of Parisi measures. We also discuss Talagrand's later program constructing pure states under extended Ghirlanda-Guerra identities and an atom at the maximal overlap, together with the structural results that followed, notably Panchenko's ultrametricity theorem and extensions of the Parisi formula. Throughout, we indicate how related contributions by many authors fit into the same long-running program across probability, analysis, and mathematical physics.
