A deflated Schur complement method for the iterative solution of a high-order discontinuous element discretization of the Poisson equation

Sumedh Joshi, Peter Diamessis

A combination of block-Jacobi and deflation preconditioning is used to solve a high-order discontinuous element-based collocation discretization of the Schur complement of the Pois…
