In the first part, we study three kinds of pre - conditioners - - block - triangular preconditioner, constraint preconditioner and block - diagonal preconditioner respective1y and fast iterative so1vers for indefinite 2 by 2 b1ock linear systems with zero ( 2, 2 ) block. the spectrum and form of eigenvalues of each preconditioned nlatrix are presented. all of the three kinds of preconditioned linear systems are so1ved by gmres ( 20 ) and theii efficiencies are cornpared
