介绍并分析了求解Hilbert空间中不适定线性算子方程的投影格式。给出了控制参数收敛的结果。重点介绍了它们的近似理论内容。对于一般源条件给出的光滑性,我们建立了收敛速度,证明在某些情况下是最优的。这项研究是通过对条件数的讨论来完成的。
We introduce and analyze projection schemes for solving ill-posed linear operator equations in Hilbert space. Control parameters are shown to yield convergence. Emphasis is on their approximation theoretic content. For smoothness given in terms of general source conditions we establish convergence rates, shown to be optimal in some cases. The study is accomplished with a discussion on condition numbers.
