A common fixed point for weak øcontractions on b-metric spaces
(2012) Aydi,H.; Bota,M.-F.; Karapinar,E.; Moradi,S.; Mathematics
In this paper, we give a common fixed point result for single-valued and multi-valued mappings satisfying a weak Øcontraction in b-metric spaces. Presented theorems extend, generalize and improve some existing results in the literature. Some examples are also given.

On Α*-Ψ Multi-Valued Operators in B-Metric Spaces and Applications
(Natural Sciences Publishing Co., 2015) Bota,M.-F.; Ilea,V.; Karapinar,E.; Mleşniţe,O.; Mathematics
In this paper, we will prove some existence and uniqueness theorems for α*-ψ contractive type operators defined over bmetric spaces. In particular, we will provide results related to Ulam-Hyers stability, well-posedness and limit shadowing. The theorems presented will extend, generalize or unify several statements currently exist in the literature on those topics.We will also give examples to illustrate the applications our results. © 2015 NSP Natural Sciences Publishing Cor.
