Parameter inference for partially observed branching processes
Simone Baldassarri, Michel Mandjes, Jiesen Wang
In this paper, we study an age-dependent branching process. In the simplest setting, the population is divided into two age groups, namely juveniles and adults. Our objective is to…
Optimal strategies for controlled growth in metastable Kawasaki dynamics
Simone Baldassarri, Maike C. de Jongh
In this paper, we develop a Markov decision process (MDP) formulation for the low--temperature metastable Ising model evolving according to Kawasaki dynamics in a finite box of the…
Infection models on dense dynamic random graphs
Simone Baldassarri, Peter Braunsteins, Frank den Hollander +1
We consider Susceptible-Infected-Recovered (SIR) models on dense dynamic random graphs, in which the joint dynamics of vertices and edges are co-evolutionary, i.e., they influence…
Metastable opinion dynamics with hidden preferences: an Ising model with neutral agents
Simone Baldassarri, Vanessa Jacquier, Alessandro Zocca
We introduce a new Ising-type framework for opinion dynamics that explicitly separates private preferences from publicly expressed binary opinions and naturally incorporates neutra…
Parameter estimation in interacting particle systems on dynamic random networks
Simone Baldassarri, Jiesen Wang
In this paper we consider a class of interacting particle systems on dynamic random networks, in which the joint dynamics of vertices and edges acts as one-way feedback, i.e., edge…
Functional central limit theorem for the subgraph count of the voter model on dynamic random graphs
Simone Baldassarri, Nikolai Kriukov
In this paper we consider two-opinion voter models on dynamic random graphs, in which the joint dynamics of opinions and graphs acts as one-way feedback, i.e., edges appear and dis…
Opinion dynamics on dense dynamic random graphs
Simone Baldassarri, Peter Braunsteins, Frank den Hollander +1
We consider two-opinion voter models on dense dynamic random graphs. Our goal is to understand and describe the occurrence of consensus versus polarisation over long periods of tim…
Homogeneous nucleation for two-dimensional Kawasaki dynamics
Simone Baldassarri, Alexandre Gaudillière, Frank den Hollander +3
This is the third in a series of three papers in which we study a lattice gas subject to Kawasaki dynamics at inverse temperature in a large finite box $Λ_β\subset \mathbb{Z}…
Critical configurations of the hard-core model on square grid graphs
Simone Baldassarri, Vanessa Jacquier, Alessandro Zocca
We consider the hard-core model on a finite square grid graph with stochastic Glauber dynamics parametrized by the inverse temperature . We investigate how the transition betwee…
Droplet dynamics in a two-dimensional rarefied gas under Kawasaki dynamics
Simone Baldassarri, Alexandre Gaudillière, Frank den Hollander +3
This is the second in a series of three papers in which we study a lattice gas subject to Kawasaki conservative dynamics at inverse temperature in a large finite box $Λ_β\sub…
Ising model on clustered networks: A model for opinion dynamics
Simone Baldassarri, Anna Gallo, Vanessa Jacquier +1
We study opinion dynamics on networks with a nontrivial community structure, assuming individuals can update their binary opinion as the result of the interactions with an external…
Metastability for Kawasaki dynamics on the hexagonal lattice
Simone Baldassarri, Vanessa Jacquier
In this paper we analyze the metastable behavior for the Ising model that evolves under Kawasaki dynamics on the hexagonal lattice in the limit of vanishing temperat…

Simone Baldassarri, Francesca R. Nardi
In this paper we analyze metastability and nucleation in the context of the Kawasaki dynamics for the two-dimensional Ising lattice gas at very low temperature. Let $Λ\subset\mathb…
Critical Droplets and sharp asymptotics for Kawasaki dynamics with weakly anisotropic interactions. Extended version
Simone Baldassarri, Francesca R. Nardi
In this paper we analyze metastability and nucleation in the context of the Kawasaki dynamics for the two-dimensional Ising lattice gas at very low temperature with periodic bounda…
Asymptotic normality of degree counts in a general preferential attachment model
Simone Baldassarri, Gianmarco Bet
We consider the preferential attachment model. This is a growing random graph such that at each step a new vertex is added and forms connections. The neighbors of the new verte…
Metastability in a lattice gas with strong anisotropic interactions under Kawasaki dynamics
Simone Baldassarri, Francesca Romana Nardi
In this paper we analyze metastability and nucleation in the context of a local version of the Kawasaki dynamics for the two-dimensional strongly anisotropic Ising lattice gas at v…
