Stability of the stationary solutions of the Allen-Cahn equation with non-constant stiffness
Paolo Buttà, Emilio N. M. Cirillo, Giulio Sciarra
We study the solutions of a generalized Allen-Cahn equation deduced from a Landau energy functional, endowed with a non-constant higher order stiffness. We assume the stiffness to…

Particle approximation of the BGK equation
Paolo Buttà, Maxime Hauray, Mario Pulvirenti
In this paper we prove the convergence of a suitable particle system towards the BGK model. More precisely, we consider an interacting stochastic particle system in which each part…

A new and stable estimation method of country economic fitness and product complexity
Vito D. P. Servedio, Paolo Buttà, Dario Mazzilli +2
We present a new metric estimating fitness of countries and complexity of products by exploiting a non-linear non-homogeneous map applied to the publicly available information on t…
