A Class of Preconditioners for non-Hermitian Positive Definite Linear Systems

摘要：

In this paper, we study a class of highly efficient preconditioners for the large sparse non-Hermitian positive definite systems of linear equations. The construction of the preconditioners is based on the Hermitian/skew-Hermitian splitting of the coefficient matrix. The presented numerical examples illustrate the effectiveness of the proposed preconditioners.
