A fixed point theorem for set-valued quasi-contractions in b-metric spaces
(Springer international Publishing Ag, 2012) Aydi, Hassen; Bota, Monica-Felicia; Karapinar, Erdal; Mitrovic, Slobodanka
In this article, we give a fixed point theorem for set-valued quasi-contraction maps in b-metric spaces. This theorem extends, unifies and generalizes several well known comparable results in the existing literature.

Ulam-Hyers Stability Results for Fixed Point Problems Via Α-Ψ Mapping in (b)-metric Space
(Hindawi Ltd, 2013) Bota, Monica-Felicia; Karapinar, Erdal; Mlesnite, Oana
We will investigate some existence, uniqueness, and Ulam-Hyers stability results for fixed point problems via alpha-psi-contractive mapping of type-(b) in the framework of b-metric spaces. The presented theorems extend, generalize, and unify several results in the literature, involving the results of Samet et al. (2012).
