Influence of triadic motifs on the dynamics of epidemic networks — •Ilja Rausch, Marco Winkler, and Haye Hinrichsen — Institute for Theoretical Physics, University of Würzburg, Am Hubland, 97074 Würzburg, Germany

Networks have become an important tool for the analysis of a variety of dynamic systems such as financial markets, coupled oscillators or epidemics. Looking at structure properties such as clustering or overrepresentation of certain motifs can lead to new insights on how networks evolve in time. In our research we want to investigate how the occurrence of specific types of triadic motifs can influence the dynamics of disease spreading on Steiner Triple Systems. In order to model the infection spreading, we consider the SIR model where susceptibles (S) interact with the infected (I) at rate β and are removed (R) due to recovery or death at rate γ. We use numerical simulations and recently developed techniques such as Node Specific Pattern Mining (NoSPaM) and Z-core analysis to investigate the effect of overrepresented triadic motifs on the clustering coefficient and network output for different values of β and γ.
