Multidimensional fixed points for generalized ψ-quasi-contractions in quasi-metric-like spaces

In this paper, we introduce the concept of a quasi-metric-like space, and by defining the w -compatibility of two mappings, we obtain multidimensional coincidence point and multidimensional fixed point theorems for generalized ψ -quasi-contractions in quasi-metric-like spaces. Our results extend the fixed point theorems in Vetro and Radenović (Appl. Math. Comput. 219:1594-1600, 2012) and references therein. MSC: 47H10, 54H25.
