Título: Numerical methods for a diffusion/fractional anti-diffusion equation

Resumo: We consider a nonlocal scalar conservation law proposed by Andrew C. Fowler to describe the dynamics of dunes. This model involves a nonlocal term which can be seen as an anti-diffusive fractional differential operator. We propose numerical schemes based on splitting methods, continuous and discontinuous Galerkin methods to approximate the solutions of this equation. Numerical stability and convergence of these schemes are investigated.
