All-at-once multigrid approaches for one-dimensional space-fractional diffusion equations
We focus on a time-dependent one-dimensional space-fractional diffusion equation with constant diffusion coefficients. An all-at-once rephrasing of the discretized problem, obtained by considering the time as an additional dimension, yields a large block linear system and paves the way for paralleli...
