Viscosity approximation method for accretive operator in Banach space (Q943684)

The authors study the strong convergence of a sequence \(\{ x_{n}\} _{n=1}^{\infty }\) in a closed convex subset \(C\) of a uniformly smooth Banach space \(X\) to a fixed point \(F(A)\) of an \(m\)-accretive operator \(A\) with a zero. Their sequence is generated by the scheme \[ x_{n+1} = \alpha _{n}f(x_{n}) + (1- \alpha _{n})J_{r_{n}}x_{n}, \quad n \geq 0, \] where \(\alpha _{n}, r_{n}\) are sequences satisfying some conditions, \(J_{r}\) denotes the resolvent \((I + rA)^{-1}\) for \(r > 0\), and \(f: C \to C\) is a fixed contractive map. Their results extend and improve those of \textit{H.-K. Xu} [J. Math. Anal. Appl. 314, No. 2, 631--643 (2006; Zbl 1086.47060)].
