AIR algebraic multigrid for a space-time hybridizable discontinuous Galerkin discretization of advection(-diffusion)

This paper investigates the efficiency, robustness, and scalability of approximate ideal restriction (AIR) algebraic multigrid as a preconditioner in the all-at-once solution of a space-time hybridizable discontinuous Galerkin (HDG) discretization of advection-dominated flows. The motivation for thi...
