A note on parameterized block triangular preconditioners for generalized saddle point problems

Eigenvalue distribution of relaxed mixed constraint preconditioner for saddle point problems

“…Here we focus on the bounds for the eigenvalues of AM −1 ω to obtain the bounds for the eigenvalues of M −1 ω A. Making this strategy to discuss the bounds for the eigenvalues of the corresponding preconditioned matrix, one can see [24,25,36,40,41,43] for more details.…”

Eigenvalue analysis of a generalized indefinite block triangular preconditioner for generalized saddle point problems

“…A special case ofP when j < 0 was studied in [23][24][25]. The ideas of [10] and [22] were combined in [13], resulting in the generalized block triangular preconditioner…”
