Parameter-Robust Preconditioning for Oseen Iteration Applied to Stationary and Instationary Navier--Stokes Control
Santolo Leveque, John W. Pearson
We derive novel, fast, and parameter-robust preconditioned iterative methods for steady and time-dependent Navier--Stokes control problems. Our approach may be applied to time-depe…

On Symmetric Positive Definite Preconditioners for Multiple Saddle-Point Systems
John W. Pearson, Andreas Potschka
We consider symmetric positive definite preconditioners for multiple saddle-point systems of block tridiagonal form, which can be applied within the MINRES algorithm. We describe s…

Saddle point preconditioners for weak-constraint 4D-Var
Jemima M. Tabeart, John W. Pearson
Data assimilation algorithms combine information from observations and prior model information to obtain the most likely state of a dynamical system. The linearised weak-constraint…
