Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have … underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their … among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural …

In this paper, we consider the following nonlinear single species diffusive system \begin{eqnarray*} \dot{x}_i(t)&=& x_i(t)\left(b_i(t)-\sum_{k=1}^{l_i}a_{ik}(t)(x_i(t))^{\beta_{ik}}\right)\\ && +\,\sum_{j=1}^{n}D_{ij}(t)(x_j(t)-x_i(t)),\quad (i,j=1,2,\ldots,n), \end{eqnarray*} where bi(t),...

An earlier study [24] concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets. We replicate this study using a more complete language model for simulations (the Schulze model combined with a...

Monte Carlo simulations of a Sznajd model show that if a near-consensus is formed out of four initially equally widespread opinions, the one which at intermediate times is second in the number of adherents usually loses out against the third-placed opinion.

In this work we have used computer models of social-like networks to show by extensive numerical simulations that … cooperation in evolutionary games can emerge and be stable on this class of networks. The amounts of cooperation reached are at … least as much as in scale-free networks but here the population model is more realistic. Cooperation is robust with respect …

In this work, we analyze gossip spreading on weighted networks. We try to define a new metric to classify weighted … complex networks using our model. The model proposed here is based on the gossip spreading model introduced by Lind et al. on … unweighted networks. The new metric is based on gossip spreading activity in the network, which is correlated with both topology …
