Modeling Heterogeneity in Networks using Uncertainty Quantification Tools
Karthikeyan Rajendran, Andreas C. Tsoumanis, Constantinos I. Siettos +2
Using the dynamics of information propagation on a network as our illustrative example, we present and discuss a systematic approach to quantifying heterogeneity and its propagatio…
Coarse-graining the dynamics of network evolution: the rise and fall of a networked society
Andreas C. Tsoumanis, Karthikeyan Rajendran, Constantinos I. Siettos +1
We explore a systematic approach to studying the dynamics of evolving networks at a coarse-grained, system level. We emphasize the importance of finding good observables (network p…
Detection of coarse-grained unstable states of microscopic/stochastic systems: a timestepper-based iterative protocol
A. C. Tsoumanis, C. I. Siettos
We address an iterative procedure that can be used to detect coarse-grained hyperbolic unstable equilibria (saddle points) of microscopic simulators when no equations at the macros…
Equation-Free Multiscale Computations in Social Networks: from Agent-based Modelling to Coarse-grained Stability and Bifurcation Analysis
A. C. Tsoumanis, C. I. Siettos, I. G. Kevrekidis +1
We focus at the interface between multiscale computations, bifurcation theory and social networks. In particular we address how the Equation-Free approach, a recently developed com…
