渐近非扩张映象不动点的三重迭代法
Three-steps Iterations Method of Fixed Point for Asymptotically Nonexpansive Mappings
【摘要】 利用赋范线性空间X的凸性模定义,以及凸性模的单调性及半紧性条件研究了渐近非扩张映射T:D→D不动点的三步迭代法.主要结果将过去一些学者研究的二步迭代推广到三步迭代,并减弱了许多条件.从而推广了同类问题的某些结果.
【Abstract】 In this paper using the definition and property of the convex modulus of norm linear spaceX,and conditions of semi-compactness,we discussed three-steps iterations method of fixed point for asymptotically nonexpansive mappings T:D→D.The main results generalized from two-steps iterations to three-steps iterations for formerly some results and weaken more conditions.Thus some similar conclusion have been obtained.
