Abstract :
The purpose of this paper is to prove some strong convergence theorems for hierarchical optimization problems of multivalued nonexpansive mappings in CAT(0) spaces by using the viscosity approximation method. Our results generalize the results of [X.-D. Liu, S.S. Chang, J. Inequal. Appl., 2013 (2013), 14 pages], [R. Wangkeeree, P. Preechasilp, J. Inequal. Appl., 2013 (2013), 15 pages], and many others. Some related results in Rtrees are also given.
