[HTML][HTML] A particle method for the homogeneous Landau equation

JA Carrillo, J Hu, L Wang, J Wu - Journal of Computational Physics: X, 2020 - Elsevier
We propose a novel deterministic particle method to numerically approximate the Landau
equation for plasmas. Based on a new variational formulation in terms of gradient flows of …

The Landau equation as a gradient flow

JA Carrillo, MG Delgadino, L Desvillettes… - arXiv preprint arXiv …, 2020 - arxiv.org
We propose a gradient flow perspective to the spatially homogeneous Landau equation for
soft potentials. We construct a tailored metric on the space of probability measures based on …

Kinetic Schauder estimates with time-irregular coefficients and uniqueness for the Landau equation

C Henderson, W Wang - arXiv preprint arXiv:2205.12930, 2022 - arxiv.org
We prove a Schauder estimate for kinetic Fokker-Planck equations that requires only H\"
older regularity in space and velocity but not in time. As an application, we deduce a weak …

Uniqueness of higher integrable solution to the Landau equation with Coulomb interactions

JL Chern, M Gualdani - arXiv preprint arXiv:1910.06216, 2019 - arxiv.org
We are concerned with the uniqueness of weak solution to the spatially homogeneous
Landau equation with Coulomb interactions under the assumption that the solution is …

A Priori Estimates for Solutions to Landau Equation Under Prodi–Serrin Like Criteria

R Alonso, V Bagland, L Desvillettes, B Lods - Archive for Rational …, 2024 - Springer
In this paper, we introduce Prodi–Serrin like criteria which enable us to provide a priori
estimates for the solutions to the spatially homogeneous Landau equation for all classical …

Global existence for an isotropic modification of the Boltzmann equation

S Snelson - Journal of Functional Analysis, 2024 - Elsevier
Motivated by the open problem of large-data global existence for the non-cutoff Boltzmann
equation, we introduce a model equation that in some sense disregards the anisotropy of …

[HTML][HTML] Analysis of a fractional cross-diffusion system for multi-species populations

A Jüngel, N Zamponi - Journal of Differential Equations, 2022 - Elsevier
The global in time existence of weak solutions to a cross-diffusion system with fractional
diffusion in the whole space is proved. The equations describe the evolution of multi-species …

Existence of smooth solutions to the Landau-Fermi-Dirac equation with Coulomb potential

W Golding, MP Gualdani, N Zamponi - arXiv preprint arXiv:2107.10463, 2021 - arxiv.org
In this paper, we prove global-in-time existence and uniqueness of smooth solutions to the
homogeneous Landau-Fermi-Dirac equation with Coulomb potential. The initial conditions …

Global Existence for an Isotropic Landau Model

D Bowman, S Ji - arXiv preprint arXiv:2403.10810, 2024 - arxiv.org
Following the recent ideas of Guillen and Silvestre in $[9] $, we prove that the Fisher
information is non-increasing along the flow of the isotropic Landau equation. We then use …

A review for an isotropic Landau model

M Gualdani, N Zamponi - PDE models for multi-agent phenomena, 2018 - Springer
We consider the equation ut= div (au∇ u− u∇ au),− Δ a= u.\displaystyle u_t= div\,(au ∇ uu
∇ au),\qquad-Δ a= u. This model has attracted some attention in the recent years and …
