Maximum principle preserving nonlocal diffusion model with Dirichlet boundary condition (2310.01221v3)
Published 2 Oct 2023 in math.AP, cs.NA, and math.NA
Abstract: In this paper, we propose nonlocal diffusion models with Dirichlet boundary. These nonlocal diffusion models preserve the maximum principle and also have corresponding variational form. With these good properties, we can prove the well-posedness and the vanishing nonlocality convergence. Furthermore, by specifically designed weight function, we can get a nonlocal diffusion model with second order convergence which is optimal for nonlocal diffusion models.
