摘要 首先给出方程有正定解的一个必要条件和充要条件,然后根据不动点理论,通过构造迭代序列,给出有解的一个充分条件。数值算例说明文中方法的有效性。 A necessary and sufficient condition is offered for the existence of the positive definite solution ,and then a iterative sequence is estalbished based on the fixed point theory to give the sufficient condition .Numerical examples illustrates the feasibility of the algorithm .
