A Characteristic Condition for Convergence of Steepest Descent Approximation to Accretive Operator Equations
摘要/Abstract
摘要:
采用Petryshyn不等式,研究了增生映像方程最速下降逼近收敛性的一个充分必要条件,并且在充分条件中,给出了一个特殊的误差估计。
Abstract:
By virtue of Petryshyn's inequality,it is obtained that a sufficient and necessary condition for convergence of steepest descent approximation to accretive operator equations, and for the sufficiency part a specific error estimation is also given.
