Preconditioning of a hybridizable discontinuous Galerkin method for the coupled Stokes--Darcy system
Parameter-robust preconditioners are designed and analyzed for the statically condensed HDG discretization of the Stokes-Darcy system by first proving uniform well-posedness and then applying operator-preconditioning frameworks.
