On the kinetic -Laplace equation with nonlocal diffusion
arXiv:2605.21080
Abstract
We study two nonlocal versions of the kinetic -Laplace equation: a Gagliardo-type model defined through differences and a Bessel-type model defined via Fourier multiplication. Using critical kinetic trajectories, we derive representation formulas adapted to the kinetic transport-diffusion geometry and establish homogeneous and scale-invariant kinetic Gagliardo-Nirenberg inequalities for nonlocal diffusion, which yield gain-of-integrability estimates for weak solutions to the kinetic -Laplace equations with nonlocal diffusion.
