Abstract

In this article, we obtain the strong convergence of the new modified Halpern iteration process

$$\begin{aligned} x_{n+1} = \alpha _{n}u + (1-\alpha _{n})T_{n}P(x_{n} + \theta _{n}(x_{n} - x_{n-1})), \ \ \ \ \ \ n=1,2,3,\ldots , \end{aligned}$$

to a common fixed point of \(\{ T_{n}\}\), where \(\{ T_{n}\}_{n=1}^{\infty }\) is a family of nonexpansive mappings on the closed and convex subset C of a Banach space X, \(P: X \longrightarrow C\) is a nonexpansive retraction, \(\{\alpha _n\} \subset [0, 1]\) and \(\{\theta _n\}\subset R^+\). Some applications of this result are also presented.
