Abstract We introduce a modified QHSS (MQHSS) iteration method for solving a class of complex symmetric linear systems, and prove that this MQHSS iteration method is convergent under certain conditions. We also consider acceleration of the MQHSS iteration by Krylov subspace methods. Numerical experiments show the good performance of the MQHSS iteration method.

一类复杂对称线性系统的改进QHSS迭代方法

摘要 我们介绍了求解一类复杂对称线性系统的改进QHSS(MQHSS)迭代方法，并证明了该MQHSS迭代方法在一定条件下是收敛的。我们还考虑了 Krylov 子空间方法对 MQHSS 迭代的加速。数值实验表明MQHSS迭代方法具有良好的性能。
