Beginner's guide to aggregation-diffusion equations

D Gómez-Castro - SeMA Journal, 2024 - Springer
The aim of this survey is to serve as an introduction to the different techniques available in
the broad field of aggregation-diffusion equations. We aim to provide historical context, key …

Minimizers for a one-dimensional interaction energy

RL Frank - Nonlinear Analysis, 2022 - Elsevier
We solve explicitly a certain minimization problem for probability measures in one
dimension involving an interaction energy that arises in the modeling of aggregation …

Classifying minimum energy states for interacting particles: regular simplices

C Davies, T Lim, RJ McCann - Communications in Mathematical Physics, 2023 - Springer
Densities of particles on R n which interact pairwise through an attractive-repulsive power-
law potential W α, β (x)=| x| α/α-| x| β/β have often been used to explain patterns produced by …

Reverse Hardy–Littlewood–Sobolev inequalities

JA Carrillo, MG Delgadino, J Dolbeault… - … Mathématiques Pures et …, 2019 - Elsevier
This paper is devoted to a new family of reverse Hardy–Littlewood–Sobolev inequalities
which involve a power law kernel with positive exponent. We investigate the range of the …

Classifying minimum energy states for interacting particles: spherical shells

C Davies, T Lim, RJ McCann - SIAM Journal on Applied Mathematics, 2022 - SIAM
Particles interacting through long-range attraction and short-range repulsion given by power-

Minimizers for an aggregation model with attactive-repulsive interaction

RL Frank, RW Matzke - arxiv preprint arxiv:2307.13769, 2023 - arxiv.org
We solve explicitly a certain minimization problem for probability measures involving an
interaction energy that is repulsive at short distances and attractive at large distances. We …
