چکیده
Multiplex networks describe systems whose interactions can be of different nature, and are fundamental to understand complexity beyond the framework simple graphs. Recently it has been pointed out that restricting attention pairwise is also a limitation, as vast majority complex include higher-order strongly affect their dynamics. Here, we propose hyper-diffusion on multiplex networks, dynamical process in which diffusion each single layer coupled with other layers thanks presence occurring when there exists link overlap. We show duplex network described by Hyper-Laplacian strength four-body among every set four replica nodes connected multilink $(1,1)$ tuned parameter $\delta_{11}\ge 0$. The reduces standard lower Laplacian, capturing at two layers, $\delta_{11}=0$. By combining tools spectral graph theory, applied topology science provide general understanding $\delta_{11}>0$, including theoretical bounds Fiedler largest eigenvalue Hyper-Laplacians asymptotic expansion spectrum for $\delta_{11}\ll1$ $\delta_{11}\gg1$. Although does not imply direct ``transfer mass" (i.e. average state conserved quantity dynamics), find dynamics relaxation steady becomes synchronous taken into account localized network.

Diffusion dynamics on multiplex networks
We study the time scales associated with diffusion processes that take place on multiplex networks, i.e., on a set of networks linked through interconnected layers. To this end, we propose the construction of a supra-laplacian matrix, which consists of a dimensional lifting of the laplacian matrix of each layer of the multiplex network. We use perturbative analysis to reveal analytically the st...
متن کاملReplicator dynamics with diffusion on multiplex networks.
In this study we present an extension of the dynamics of diffusion in multiplex graphs, which makes the equations compatible with the replicator equation with mutations. We derive an exact formula for the diffusion term, which shows that, while diffusion is linear for numbers of agents, it is necessary to account for nonlinear terms when working with fractions of individuals. We also derive the...
متن کاملSuppressing disease spreading by using information diffusion on multiplex networks
Although there is always an interplay between the dynamics of information diffusion and disease spreading, the empirical research on the systemic coevolution mechanisms connecting these two spreading dynamics is still lacking. Here we investigate the coevolution mechanisms and dynamics between information and disease spreading by utilizing real data and a proposed spreading model on multiplex n...

متن کاملOptimal resource diffusion for suppressing disease spreading in multiplex networks
Resource diffusion is an ubiquitous phenomenon, but how it impacts epidemic spreading has received little study. We propose a model that couples epidemic spreading and resource diffusion in multiplex networks. The spread of disease in a physical contact layer and the recovery of the infected nodes are both strongly dependent upon resources supplied by their counterparts in the social layer. The...
