Abstract

In this paper, we study the convergence of  SP-iteration scheme for a class of mappings satisfying the condition (C) and prove $\Delta$-convergence as well as strong convergence theorems in Hadamard spaces. Our results generalize and improve several relevant results of the existing literature.
