APPROXIMATION OF FIXED POINTS OF ASYMPTOTICALLY κ-STRICT PSEUDOCONTRACTIONS IN A BANACH SPACE

In this paper, weak convergence theorems of a finite family of asymptotically k-strict pseudo-contractions are established in the framework of 2-uniformly smooth and uniformly convex Banach spaces.

Keywords:
