The authors are concerned with the analysis of two classes of parametrized block triangular preconditioners for generalized saddle point problems, which generalize the common block diagonal and triangular preconditioners. They provide information about the eigenvalues of the preconditioned matrix and estimates for the interval containing the real eigenvalues.
