Split-Spectrum Based Distributed State Estimation for Linear Systems
Lili Wang, Ji Liu, Brian B. O. Anderson +1
This paper studies a distributed state estimation problem for both continuous- and discrete-time linear systems. A simply structured distributed estimator (comprising interconnecte…
On a Network SIS Epidemic Model with Cooperative and Antagonistic Opinion Dynamics
Baike She, Ji Liu, Shreyas Sundaram +1
We propose a mathematical model to study coupled epidemic and opinion dynamics in a network of communities. Our model captures SIS epidemic dynamics whose evolution is dependent on…
On Spectral Properties of Signed Laplacians with Connections to Eventual Positivity
Wei Chen, Dan Wang, Ji Liu +5
Signed graphs have appeared in a broad variety of applications, ranging from social networks to biological networks, from distributed control and computation to power systems. In t…
A Distributed Observer for a Continuous-Time Linear System with time-varying network
Lili Wang, Ji Liu, A. Stephen Morse
A simply structured distributed observer is described for estimating the state of a continuous-time, jointly observable, input-free, linear system whose sensed outputs are distribu…
Maxwells Demon: Controlling Entropy via Discrete Ricci Flow Over Networks
Romeil Sandhu, Ji Liu
In this work, we propose to utilize discrete graph Ricci flow to alter network entropy through feedback control. Given such feedback input can reverse entropic changes, we adapt th…
A Distributed Observer for a Discrete-Time Linear System
Lili Wang, Ji Liu, A. Stephen Morse +1
A simply structured distributed observer is described for estimating the state of a discrete-time, jointly observable, input-free, linear system whose sensed outputs are distribute…
Cooperative opinion dynamics on multiple interdependent topics: Modeling and analysis
Hyo-Sung Ahn, Quoc Van Tran, Minh Hoang Trinh +3
To model the interdependent couplings of multiple topics, we develop a set of rules for opinion updates of a group of agents. The rules are used to design or assign values to the e…
A Generalized Discrete-Time Altafini Model
L. Wang, J. Liu, A. S. Morse +2
A discrete-time modulus consensus model is considered in which the interaction among a family of networked agents is described by a time-dependent gain graph whose vertices corresp…
A Distributed Algorithm for Solving a Linear Algebraic Equation
Shaoshuai Mou, Ji Liu, A. Stephen Morse
A distributed algorithm is described for solving a linear algebraic equation of the form assuming the equation has at least one solution. The equation is simultaneously solv…
Distributed Evaluation and Convergence of Self-Appraisals in Social Networks
Xudong Chen, Ji Liu, M. -A. Belabbas +2
We consider in this paper a networked system of opinion dynamics in continuous time, where the agents are able to evaluate their self-appraisals in a distributed way. In the model…
