Summary: In this paper, we study iteration methods for approximating a common fixed point of a family of nonlinear mappings in a Banach space. First, we discuss some properties of relatively nonexpansive mappings and strongly relatively nonexpansive mappings. Then we obtain strong convergence theorems for a sequence of relatively nonexpansive mappings by using two hybrid projection methods. Using these results, we study the problem of finding a zero of a maximal monotone operator and a common fixed point of a countable family of relatively nonexpansive mappings.
