Let E be a real normed linear space and E∗ its dual. In a recent work, Chidume et al. [Chidume, C. E. and Idu, K. O., Approximation of zeros of
bounded maximal monotone mappings, solutions of hammerstein integral equations and convex minimizations problems, Fixed Point Theory and Applications, 97 (2016)] introduced the new concepts of J-fixed points and J-pseudocontractive mappings and they shown that a mapping A : E → 2
E∗
is
monotone if and only if the map T := (J −A) : E → 2
E∗
is J-pseudocontractive, where J is the normalized duality mapping of E. It is our purpose
in this work to introduce an algorithm for approximating J-fixed points of J-pseudocontractive mappings. Our results are applied to approximate
zeros of monotone mappings in certain Banach spaces. The results obtained here, extend and unify some recent results in this direction for the
class of maximal monotone mappings in uniformly smooth and strictly convex real Banach spaces. Our proof is of independent interest.
