The diffusive limit for Carleman-type kinetic models

We study the limiting behavior of the Cauchy problem for a class of Carleman-like models in the diffusive scaling with data in the spaces L, 1 ≤ p ≤ ∞. We show that, in the limit, the solution of such models converges towards the solution of a nonlinear diffusion equation with initial values determined by the data of the hyperbolic system. When the data belong to L, a condition of conservation ...

Internal null stabilization for some diffusive models of population dynamics

We investigate the large-time behavior of the solutions to some Fisher-type models with nonlocal terms describing the dynamics of biological populations with diffusion, logistic term and migration. Two types of logistic terms are taken into account. A necessary condition and a sufficient condition for the internal null stabilizability of the solution to a Fisher model with nonlocal term are pro...

Diffusive and nondiffusive population models

The modeling of populations is of great importance in ecology and economy, for instance, to describe predator-prey and competition interactions, to predict the dynamics of cell divisions and infectious diseases, and to manage renewable resources (harvesting). Population models describe the change of the number of species due to birth, death, and movement from position to position (in space) or ...

An anti-diffusive scheme for viability problems

This paper is concerned with the numerical approximation of viability kernels. The method described here provides an alternative approach to the usual viability algorithm. We first consider a characterization of the viability kernel as the value function of a related optimal control problem, and then use a specially relevant numerical scheme for its approximation. Since this value function is d...

Diffusive thermal dynamics for the Ising ferromagnet.

We introduce a thermal dynamics for the Ising ferromagnet where the energy variations occurring within the system exhibit a diffusive character typical of thermalizing agents such as, e.g., localized excitations. Time evolution is provided by a walker hopping across the sites of the underlying lattice according to local probabilities depending on the usual Boltzmann weight at a given temperatur...
