In this paper we introduce the notion of (α∗ − ψ)Ćirić-type contractive multivalued operator and investigate the existence and uniqueness of fixed point for such a mapping in b-metric spaces. The wellposedness of the fixed point problem and the Ulam-Hyres stability is also studied. c ©2016 All rights reserved.
