On the construction of deflation-based preconditioners (English)
0 references
New effective condition number bounds for deflated systems, both with and without preconditioning are given. Subdomain deflation is very easy to implement, and the method can be very efficiently implemented on distributed memory parallel computers. Numerical experiments for a steady-state are included.
