Self-similarity and diffusive limits for linear kinetic equations: a Wild sum approach

José A. Cañizo, Stéphane Mischler, Niccolò Tassi

We prove that linear collisional kinetic equations in the whole space without confinement mechanism display a long-time self-similar behaviour. This drastically improves the recent…

Sharp asymptotic behaviour of symmetric and non-symmetric solutions of the Heat Equation in the Hyperbolic Space

José Alfredo Cañizo, Alejandro Gárriz, Diego Alfonso Marín

In this work we study the large-time behaviour of solutions of the Heat Equation in the hyperbolic space , providing precise speeds of convergence in and $L^\in…

A uniform-in-time nonlocal approximation of the standard Fokker-Planck equation

José A. Cañizo, Niccolò Tassi

We study a nonlocal approximation of the Fokker-Planck equation in which we can estimate the speed of convergence to equilibrium in a way which does not degenerate as we approach t…

Comparison principles and asymptotic behavior of delayed age-structured neuron models

María J Cáceres, José A Cañizo, Nicolas Torres

In the context of neuroscience the elapsed-time model is an age-structured equation that describes the behavior of interconnected spiking neurons through the time since the last di…

On the local stability of the elapsed-time model in terms of the transmission delay and interconnection strength

María J. Cáceres, José A Cañizo, Nicolas Torres

The elapsed-time model describes the behavior of interconnected neurons through the time since their last spike. It is an age-structured non-linear equation in which age correspond…

Large-time estimates for the Dirichlet heat equation in exterior domains

José A. Cañizo, Alejandro Gárriz, Fernando Quirós

We give large-time asymptotic estimates, both in uniform and norms, for solutions of the Dirichlet heat equation in the complement of a bounded open set of sat…
