Nonlocal modeling of opinion alignment and environmental feedback: Spatial aggregation and non-consensus patterns

意见对齐与环境反馈的非局部建模：空间聚集与非共识模式

Rui Wang, Yunfeng Xiong, Zhengru Zhang, Xiaofei Zhao

专题命中 Agent评测 ：agent(abstract)

AI总结 提出一个注意力介导反馈的空间意见动力学模型，通过非局部对齐与注意力场耦合，推导出非局部对流-交叉扩散系统，分析显示注意力反馈扩大非共识聚类参数区间，促进空间异质性。
