Robustness Of Complex Networks To Global Perturbations, Samuel Heiserman
Robustness Of Complex Networks To Global Perturbations, Samuel Heiserman
Graduate Dissertations and Theses
This thesis studies the robustness of complex dynamical networks with non-trivial topologies against global perturbations, following Robert May’s seminal work on network stability, in order to find critical stability thresholds of global perturbations and to determine if their impact varies across different network topologies. Numerical analysis is used as the primary research method. Dynamical networks are randomly generated in the form of a coefficient matrix of stable linear differential equations. The networks are then inflicted with global perturbation (i.e., addition of another random matrix with varying magnitudes) and their stabilities are tested for each perturbation magnitude, to determine at what …
