## Abstract A class of constraint preconditioners for solving two‐by‐two block linear equations with the (1,2)‐block being the transpose of the (2,1)‐block and the (2,2)‐block being zero was investigated in a recent paper of Cao (__Numer. Math.__ 2006; **103**:47–61). In this short note, we extend

Three domain decomposition methods for saddle point problems are introduced and compared. The first two are blockdiagonal and block-triangular preconditioners with diagonal blocks approximated by an overlapping Schwarz technique with positive definite local and coarse problems. The third is an overl
