Extreme vulnerability to intruder attacks destabilizes network dynamics
Amirhossein Nazerian, Sahand Tangerami, Malbor Asllani +3
Consensus, synchronization, formation control, and power grid balance are examples of desirable dynamical states that arise in networks. Here we investigate how such states can be…
The Frequency Response of Networks as Open Systems
Amirhossein Nazerian, Malbor Asllani, Melvyn Tyloo +2
Many biological, technological, and social systems can be effectively described as networks of interacting subsystems. Typically, these networks are not isolated objects, but inter…
Open networks in discrete time: Passing vs blocking behavior
Amirhossein Nazerian, MAlbor Asllani, Melvyn Tyloo +1
This paper presents a unified framework for analyzing the input-output behavior of discrete time complex networks viewed as open systems. Importantly, we focus on systems that are…
Bridging the Gap between Reactivity, Contraction, and Finite-Time Lyapunov Exponents
Amirhossein Nazerian, Francesco Sorrentino, Zahra Aminzare
Reactivity, contractivity, and Lyapunov exponents are powerful tools for studying the stability properties of dynamical systems and have been extensively investigated in the litera…
The Efficiency of Synchronization Dynamics and the Role of Network Syncreactivity
Amirhossein Nazerian, Joseph D Hart, Matteo Lodi +1
Synchronization of coupled oscillators is a fundamental process in both natural and artificial networks. While much work has investigated the asymptotic stability of the synchronou…
