Abstract
In this paper, we use the iterative method proposed by Zegeye and Shahzad [H. Zegeye, N. Shahzed,
Fixed Point Theory Appl., 2013 (2013), 12 pages] which converges strongly to the common minimum-norm
fixed point of a finite family of \(\sigma\)-asymptotically quasi-nonexpansive mappings. As consequence, convergence
results to a common minimum-norm fixed point of a finite family of asymptotically nonexpansive mappings
is proved. Our result generalize and improve a recent result of Zegeye and Shahzad [H. Zegeye, N. Shahzed,
Fixed Point Theory Appl., 2013 (2013), 12 pages]. In the sequel, we apply our main result to find solution
of minimizer of a continuously Frechet-differentiable convex functional which has the minimum norm in
Hilbert spaces.
