Parameter estimation for graphon-interacting particle systems from discrete observations

Chiara Amorino, Matteo Sfragara

In this paper, we address the joint parameter estimation of drift and diffusion coefficients for heterogeneously interacting particle systems. Unlike the homogeneous setting, the i…

Surviving from the tip of a cone in competing first-passage percolation

Daniel Ahlberg, Maria Deijfen, Matteo Sfragara

In two-type first passage percolation on , two entities compete to capture the sites of the lattice. The entities spread between nearest neighbor sites at times speci…

The Ising Model on a Two-Community Stochastic Block Model

Alessandra Bianchi, Vanessa Jacquier, Matteo Sfragara

We study the Ising model on a two-community stochastic block model, where spins are split into two equal groups with inter-community interaction parameter . We pro…

Mean field stable matchings

Daniel Ahlberg, Maria Deijfen, Matteo Sfragara

Consider the complete bipartite graph on vertices where the edges are equipped with i.i.d. exponential costs. A matching of the vertices is stable if it does not contain any…

From stability to chaos in last-passage percolation

Daniel Ahlberg, Maria Deijfen, Matteo Sfragara

We study the transition from stability to chaos in a dynamic last passage percolation model on with random weights at the vertices. Given an initial weight configura…

Chaos, concentration and multiple valleys in first-passage percolation

Daniel Ahlberg, Maria Deijfen, Matteo Sfragara

A decade and a half ago Chatterjee established the first rigorous connection between anomalous fluctuations and a chaotic behaviour of the ground state in certain Gaussian disorder…
