Abstract

This paper provides some historical comments on the study of the Fermi, Pasta, and Ulam (FPU) paper and its influence on the development of the theory of chaos. We also discuss some problems raised in the FPU paper and the links of these problems to such contemporary notions in chaos theory as ergodicity, mixing, recurrences, pseudochaos, kinetics, intermittency, etc.

摘要

本文对费米（Fermi）、帕斯塔（Pasta）和乌拉姆（Ulam）（FPU）论文的研究及其对混沌理论发展的影响提供了一些历史评论。我们还讨论了FPU论文中提出的一些问题，以及这些问题与混沌理论中诸如遍历性、混合性、递归性、伪混沌、动力学、间歇性等当代概念的联系。
