چکیده
our contribution in this paper is to propose an iterative algorithm which does not require prior knowledge of operator norm and prove a strong convergence theorem for approximating a solution of split equality fixed point problem for quasi-nonexpansive mappings in a real hilbert space. so many have used algorithms involving the operator norm for solving split equality fixed point problem, but as widely known the computation of these algorithms may be difficult and for this reason, some researchers have recently started constructing iterative algorithms with a way of selecting the step-sizes such that the implementation of the algorithm does not require the calculation or estimation of the operator norm. to the best of our knowledge most of the works in literature that do not involve the calculation or estimation of the operator norm only obtained weak convergence results. in this paper, by appropriately modifying the simultaneous iterative algorithm introduced by zhao, we state and prove a strong convergence result for solving split equality problem. we present some applications of our result and then give some numerical example to study its efficiency and implementation at the end of the paper.

متن کاملSolving proximal split feasibility problems without prior knowledge of operator norms
Abstract In this paper our interest is in investigating properties and numerical solutions of Proximal Split feasibility Problems. First, we consider the problem of finding a point which minimizes a convex function f such that its image under a bounded linear operator A minimizes another convex function g. Based on an idea introduced in [9], we propose a split proximal algorithm with a way of s...
