英文摘要：
We show that the emergence of systemic risk in complex systems can be understood from the evolution of functional networks representing interactions inferred from fluctuation correlations between macroscopic observables. Specifically, we analyze the long-term collective dynamics of the New York Stock Exchange between 1926-2016, showing that periods marked by systemic crisis, viz., around the Great Depression of 1929-33 and the Great Recession of 2007-09, are associated with emergence of frustration indicated by the loss of structural balance in the interaction networks. During these periods the dominant eigenmodes characterizing the collective behavior exhibit delocalization leading to increased coherence in the dynamics. The topological structure of the networks exhibits a slowly evolving trend marked by the emergence of a prominent core-periphery organization around both of the crisis periods.

中文摘要：
我们表明，复杂系统中系统性风险的出现可以从功能网络的演化中理解，这些功能网络表示从宏观观测值之间的波动相关性推断出的相互作用。具体而言，我们分析了1926年至2016年期间纽约证券交易所的长期集体动态，表明以系统性危机为标志的时期，即：。，1929-33年的大萧条和2007-09年的大衰退，都与互动网络中结构平衡的丧失所表明的挫折感的出现有关。在这些时期，表征集体行为的主要本征模表现出离域性，从而增加了动力学的一致性。网络的拓扑结构呈现出缓慢发展的趋势，在这两个危机时期都出现了一个突出的核心-外围组织。
