On the Numerical Solution of the Poisson Equation in the Smoothed Particle Hydrodynamics

Studies in Applied Mathematics, Volume 157, Issue 4, October 2026.
ABSTRACT In the present work, we address some aspects related to the numerical solution of the Poisson equation within the framework of the Smoothed Particle Hydrodynamics (SPH). In this case, the Poisson equation is solved using nonlocal, kernel‐based discretizations of the differential operators (i.e., gradient, divergence, and Laplacian operators ...

On trilinear singular Brascamp–Lieb integrals

Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.
Abstract We classify trilinear singular Brascamp–Lieb forms, extending a result of Demeter and Thiele. We use results from the representation theory of finite‐dimensional algebras, namely the classification of indecomposable representations of the four subspace quiver.

Fractional Laplacian in conformal geometry

In this note, we study the connection between the fractional Laplacian operator that appeared in the recent work of Caffarelli and Silvestre and a class of conformally covariant operators in conformal geometry.Peer ...

Eigenvalues homogenization for the fractional \(p\)-Laplacian

Electronic Journal of Differential Equations, 2016
In this work we study the homogenization for eigenvalues of the fractional p-Laplace operator in a bounded domain both with Dirichlet and Neumann conditions. We obtain the convergence of eigenvalues and the explicit order of the convergence rates when periodic weights are considered.
