KW - Additive Schwarz method, PCG, Matrix analysis.
AB - <p style="text-align: justify;">It is well known the order of preconditional matrix by using additive Schwarz methods. In order to estimate the resulted PCG iteration counts, the related leading term before the order is given in this paper.</p>
