The eigenpair properties of the preconditioned matriz for general saddle point problems

摘要：

In this paper, we study the eigenpair properties of the general saddle point problems with preconditioners which contain real parameters. We will give the minimal polynomial and the eigenvectors of these preconditioned matrices, and also show that the eigenvalues of preconditioned matrices are real or preconditioned matrices are positive definite if we choose appropriate parameters.
