摘要:

不适定问题应用广泛. 该文针对自共轭算子方程的特征值是实数的特殊性质, 建立了自共轭算子方程不适定问题的复参数迭代算法. 证明了算法的正则性, 保证解的误差估计达到最优的收敛阶数, 并通过数值实验对结论进行了验证.

关键词: 不适定问题, 正则化策略, 收敛阶

Abstract:

Ill-posed problems are used widely. The authors take advantage of the special character of the self-adjoint compact operator equation, establishing its iterative method with complex parameter. Furthermore, they prove the regularization of this method and best orders of convergence. Finally, they examines the result by numerical experiments.

Key words: Ill-posed problem, Regularization, Orders of convergence
