Selected Publications

Complex networks have been successfully used to describe the spreading of a disease in populations of interacting individuals. Conversely, pairwise interactions are often not enough to characterize processes of social contagion, such as opinion formation or the adoption of novelties, where more complex dynamics of peer influence and reinforcement mechanisms are at work. Here we introduce a high-order model of social contagion in which a social system is represented by a simplicial complex and the contagion can occur, and with different transmission rates, not only over the links but also through interactions in groups of different sizes. Numerical simulations of the model on synthetic simplicial complexes highlight the emergence of novel phenomena such as the appearance of an explosive transition induced by the high-order interactions. We show analytically that the transition is discontinuous with the formation of a bistable region where healthy and endemic states co-exist. Our results represent a first step to understand the role of high-order interactions in complex systems

We introduce a model for the emergence of innovations, in which cognitive processes are described as random walks on the network of links among ideas or concepts, and an innovation corresponds to the first visit of a node. The transition matrix of the random walk depends on the network weights, while in turn the weight of an edge is reinforced by the passage of a walker. The presence of the network naturally accounts for the mechanism of the adjacent possible, and the model reproduces both the rate at which novelties emerge and the correlations among them observed empirically. We show this by using synthetic networks and by studying real data sets on the growth of knowledge in different scientific disciplines. Edge-reinforced random walks on complex topologies offer a new modeling framework for the dynamics of correlated novelties and another example of co-evolution of processes and networks.
