符号网络上的动力学

Dynamics over Signed Networks

Guodong Shi, Claudio Altafini, John S. Baras

摘要:

有符号网络是每个链路都与正号或负号相关联的网络。节点在这种签名网络上相互作用的模型,其中两种不同类型的相互作用分别沿着正链接和负链接发生,来自各种生物,社会,政治和经济系统。作为对传统的正链接DeGroot动力学的修改,沿着负链接的两种基本类型的负相互作用,即对立规则和排斥规则,已经在文献中提出和研究。本文综述了确定性或随机符号网络上这类动力学在统一的代数-图解方法下的一些基本收敛结果。我们表明,一个系统的工具,研究节点状态演化的签署网络,可以得到利用广义Perron-Frobenius理论,图论和初等代数递归。

英文摘要:

A signed network is a network with each link associated with a positive or negative sign. Models for nodes interacting over such signed networks, where two different types of interactions take place along the positive and negative links, respectively, arise from various biological, social, political, and economic systems. As modifications to the conventional DeGroot dynamics for positive links, two basic types of negative interactions along negative links, namely the opposing rule and the repelling rule, have been proposed and studied in the literature. This paper reviews a few fundamental convergence results for such dynamics over deterministic or random signed networks under a unified algebraic-graphical method. We show that a systematic tool of studying node state evolution over signed networks can be obtained utilizing generalized Perron-Frobenius theory, graph theory, and elementary algebraic recursions.
