摘要：
A preconditioned AOR iterative method is proposed with the preconditioner I + S(alpha beta)* p. Some comparison theorems are given when the coefficient matrix of linear system A is an irreducible L matrix. The convergence rate of AOR iterative method with the preconditioner I + S(alpha beta)* is faster than the convergence rate with the preconditioner I + S(alpha) by Li et al. Numerical example verifies comparison theorems.
