Preconditioning transformations of adjoint systems for evolution equations

Brian K. Tran, Ben S. Southworth, Hannah F. Blumhoefer +1

Achieving robust control and optimization in high-fidelity physics simulations is extremely challenging, especially for evolutionary systems whose solutions span vast scales across…

A note on $2 \times 2$ block-diagonal preconditioning

Ben S. Southworth, Samuel A. Olivier

For 2x2 block matrices, it is well-known that block-triangular or block-LDU preconditioners with an exact Schur complement (inverse) converge in at most two iterations for fixed-po…
