中文简介: | 网络在现代社会中无处不在。将我们与世界其他地方联系起来并使信息流通成为可能的万维网就是最明显的例子。然而,它只是我们所处的众多网络之一。我们的社交生活是围绕着朋友和同事的网络组织起来的。这些网络决定我们的信息,影响我们的观点,并塑造我们的政治态度。它们还常常通过重要但薄弱的纽带把我们同美国和世界上的每一个人联系在一起。经济和金融市场看起来更像是网络,而不是匿名市场。企业与相同的供应商和客户进行交互,并使用类似web的供应链。银行之间以及消费者、公司和银行之间的金融联系也形成了资金流动和风险分担的网络。金融市场的系统性风险往往来自于该金融网络中产生的交易对手风险。食物链、相互作用的生物系统以及流行病的传播和遏制是另一些具有显著网络结构的自然和社会现象。本课程将介绍学习网络的工具。它将展示某些共同原则如何渗透这些不同网络的功能,以及与健壮性、脆弱性和相互联系有关的相同问题如何在几种不同类型的网络中出现。 |
课程简介: | Networks are ubiquitous in our modern society. The World Wide Web that links us to and enables information flows with the rest of the world is the most visible example. It is, however, only one of many networks within which we are situated. Our social life is organized around networks of friends and colleagues. These networks determine our information, influence our opinions, and shape our political attitudes. They also link us, often through important but weak ties, to everybody else in the United States and in the world. Economic and financial markets also look much more like networks than anonymous marketplaces. Firms interact with the same suppliers and customers and use Web-like supply chains. Financial linkages, both among banks and between consumers, companies and banks, also form a network over which funds flow and risks are shared. Systemic risk in financial markets often results from the counterparty risks created within this financial network. Food chains, interacting biological systems and the spread and containment of epidemics are some of the other natural and social phenomena that exhibit a marked networked structure. This course will introduce the tools for the study of networks. It will show how certain common principles permeate the functioning of these diverse networks and how the same issues related to robustness, fragility, and interlinkages arise in several different types of networks. |
