摘要
在L~p(1
第二类Fredholm积分方程提出了一种新的投影算法,对积分算子进行均值投影,给出了算法的先验估计和后验估计.数值算例进一步验证了算法的合理性和有效性.
This paper gives a new projection method for the numerical solution of Fredholm integral equation of the second kind in L~p(1 < p < ∞) space. And discussed integral operator with mean projection. A priori estimate and a posteriori estimate are given in detail. Finally, two specific numerical examples are shown to demonstrate the rationality and availability of the proposed algorithm.
