In this paper, we consider a countable family of surjective mappings {Tn}n∈N satisfying certain quasi-contractive conditions. We also construct a convergent sequence{xn}n∈N by the quasi-contractive conditions of{Tn}n∈N and the boundary condition of a given complete and closed subset of a cone metric space X with convex structure, and then prove that the unique limit x of{xn}n∈N is the unique common fixed point of{Tn}n∈N. Finally, we will give more generalized common fixed point theorem for mappings{Ti,j }i,j∈N. The main theorems in this paper generalize and improve many known common fixed point theorems for a finite or countable family of mappings with quasi-contractive conditions.
