Fixed and common fixed point theorems in frame of quasi metric spaces under contraction condition based on ultra distance functions
In this paper, we introduce the notion of ultra distance function. Based on the notion of ultra distance function, we introduce the definitions of (k, ψ, L)-quasi contractions of type (I) and type (II) in the frame of quasi metric spaces. We employ our new definitions to construct and prove many fi...
