Network evolution with self-reinforcement

Shankar Bhamidi, Remco van der Hofstad, Frank den Hollander +1

We study a new class of preferential attachment trees with \emph{self-reinforcement}. At each time, each vertex is assigned a weight equal to the cumulative sum over past times of…

Universality of the local limit of preferential attachment models

Alessandro Garavaglia, Rajat Subhra Hazra, Remco van der Hofstad +1

We study preferential attachment models where vertices enter the network with i.i.d. random numbers of edges that we call the out-degree. We identify the local limit of such models…

Non-equilibrium coagulation processes and subcritical percolation on evolving networks

Sayan Banerjee, Shankar Bhamidi, Remco van der Hofstad +1

We investigate percolation on growing networks where the evolution of connected components resembles a non-equilibrium version of the multiplicative coalescent. The supercritical $…

Ising model on preferential attachment models

Remco van der Hofstad, Rounak Ray

We study the Ising model on affine preferential attachment models with general parameters. We identify the thermodynamic limit of several quantities, arising in the large graph lim…

Stochastic processes on preferential attachment models

Rounak Ray

In real life, networks are dynamic in nature; they grow over time and often exhibit power-law degree sequences. To model the evolving structure of the internet, Barabási and Alber…
