Özet

The studies about hybrid mappings are mainly focused for single-valued mappings in Hilbert spaces. We define a new class of multivalued mappings in CAT (kappa) spaces which contains the multivalued nonexpansive mappings, alpha-nonexpansive mappings and some hybrid mappings such as (alpha, beta)-hybrid mappings and we study existence and convergence of this new class of mappings on CAT(kappa) spaces which is more general than CAT(0) spaces and also non-Euclidean generalization of Hilbert spaces.
