A new one-step iterative process for approximating common fixed points of a countable family of quasi-nonexpansive multivalued mappings in CAT(0) spaces

‎In this paper‎, ‎we propose a new onestep iterative process for a‎ ‎countable family of quasinonexpansive multivalued mappings in a‎ ‎CAT(0) space‎. ‎We also prove strong and Delta-convergence theorems‎ ‎of the proposed iterative process under some control conditions‎. ‎Our‎ ‎main results extend and generalize many results in the literature.
