Nonlinear ψ-quasi-contractions of Ćirić-type in partial metric spaces

摘要

In this paper we obtain results of fixed and common fixed points for self-mappings satisfying a nonlinear contractive condition of Ćirić-type in the framework of partial metric spaces. We also prove results of fixed point for self-mappings satisfying an ordered nonlinear contractive condition in the setting of ordered partial metric spaces.
