Quantifying opinion homophily in online social networks: A bounded confidence perspective
Yangyang Luan, Camilla Ancona, Carmela Bernardo +6
The concept of homophily is pervasive in online social media. While many empirical studies have relied on external sociodemographic traits to investigate it, significantly less is…
Signed DeGroot-Friedkin Dynamics with Interdependent Topics
Yangyang Luan, Muhammad Ahsan Razaq, Xiaoqun Wu +1
This paper investigates DeGroot-Friedkin (DF) dynamics over signed influence networks with interdependent topics. We propose a multi-topic signed framework that combines repelling…
Non-trivial consensus on directed signed matrix-weighted networks with compound measurement noises and time-varying topologies
Tianmu Niu, Xiaoqun Wu
This paper studies non-trivial consensus--a relatively novel and unexplored convergence behavior--on directed signed matrix-weighted networks subject to both additive and multiplic…
Non-Trivial Consensus on Directed Matrix-Weighted Networks with Cooperative and Antagonistic Interactions
Tianmu Niu, Bing Mao, Xiaoqun Wu +1
This paper investigates the non-trivial consensus problem on directed signed matrix-weighted networks\textemdash a novel convergence state that has remained largely unexplored desp…
