Predicting the response of structurally altered and asymmetrical networks

Area of Science:

• Complex Systems
• Network Science
• Dynamical Systems Theory

Background:

• Existing research often assumes symmetrical interactions and additive changes.
• Investigating asymmetrical and multiplicative alterations presents a significant challenge in network dynamics.

Purpose of the Study:

• To develop a framework for analyzing the effects of general structural alterations on coupled dynamical systems.
• To understand how non-normal and asymmetrical interactions modify system responses.

Main Methods:

• Introduction of a novel framework to approximate averaged network node responses.
• Analysis of general structural alterations, including non-normal and asymmetrical coupling.

Main Results:

• Both asymmetry and non-normality in structural alterations influence global and local system responses.
• The impact of alterations manifests at different temporal orders.

Conclusions:

• The study provides a method to quantify the effects of complex interaction changes.
• Identifies specific network nodes most sensitive to structural modifications, aiding targeted analysis.
