The spread of innovations in social networks

A Montanari, A Saberi - Proceedings of the National Academy of Sciences, 2010‏ - pnas.org
Which network structures favor the rapid spread of new ideas, behaviors, or technologies?
This question has been studied extensively using epidemic models. Here we consider a …

[ספר][B] Entropy

A Greven, G Keller, G Warnecke - 2014‏ - books.google.com
The concept of entropy arose in the physical sciences during the nineteenth century,
particularly in thermodynamics and statistical physics, as a measure of the equilibria and …

Tunneling and metastability of continuous time Markov chains

J Beltran, C Landim - Journal of Statistical Physics, 2010‏ - Springer
We propose a definition of tunneling and of metastability for a continuous time Markov
process on countable state spaces. We obtain sufficient conditions for a irreducible positive …

Metastability of synchronous and asynchronous dynamics

ENM Cirillo, V Jacquier, C Spitoni - Entropy, 2022‏ - mdpi.com
Metastability is a ubiquitous phenomenon in nature, which interests several fields of natural
sciences. Since metastability is a genuine non-equilibrium phenomenon, its description in …

Metastability and nucleation for the Blume-Capel model. Different mechanisms of transition

ENM Cirillo, E Olivieri - Journal of Statistical Physics, 1996‏ - Springer
We study metastability and nucleation for the Blume-Capel model: a ferromagnetic nearest
neighbor two-dimensional lattice system with spin variables taking values in {− 1, 0,+ 1}. We …

Markov chains with exponentially small transition probabilities: first exit problem from a general domain. I. The reversible case

E Olivieri, E Scoppola - Journal of statistical physics, 1995‏ - Springer
We consider general ergodic aperiodic Markov chains with finite state space whose
transition probabilities between pairs of different communicating states are exponentially …

On the essential features of metastability: tunnelling time and critical configurations

F Manzo, FR Nardi, E Olivieri, E Scoppola - Journal of Statistical Physics, 2004‏ - Springer
Abstract We consider Metropolis Markov chains with finite state space and transition
probabilities of the form P (η, η')= q (η, η') e^-β H (η')-H (η) _+ for given energy function H …

Convergence to equilibrium in local interaction games

A Montanari, A Saberi - ACM SIGecom Exchanges, 2009‏ - dl.acm.org
We study a simple game-theoretic model for the spread of an innovation in a network. The
diffiusion of the innovation is modeled as the dynamics of a coordination game in which the …
