基于拓扑相互作用的有限注意力动态模型
Modeling limited attention in opinion dynamics by topological interactions
摘要：
这项工作探讨了意见依赖连接的意见动态模型。我们的出发点是，个人与同龄人互动的能力有限。出于这一观察，我们提出了一个连续时间的意见动态模型，使互动发生在有限数量的同行：我们指的是这些相互作用的拓扑，而不是度量的相互作用，假设在经典的有界置信模型。我们观察到，拓扑相互作用产生的平衡是非常强大的扰动。
英文摘要：
This work explores models of opinion dynamics with opinion-dependent connectivity. Our starting point is that individuals have limited capabilities to engage in interactions with their peers. Motivated by this observation, we propose a continuous-time opinion dynamics model such that interactions take place with a limited number of peers: we refer to these interactions as topological, as opposed to metric interactions that are postulated in classical bounded-confidence models. We observe that topological interactions produce equilibria that are very robust to perturbations.
