In this study, we examined some fixed point theorems in non-full metric spaces. We define the notions of α-lower semi-continuous , w-α-distance, w_0-α– distance, w-α-rational contraction and generalized w-α-rational contraction mapping. We also give related theorem and example. Then, we prove Banach’s fixed-point theorem thanks to the concept w-α- distance in metric spaces equipped with an abritrary binary relation. Also, w-α- rational contraction mapping and generalized w-α-rational contraction mapping are defined and by using these definitions, the theorem related fixed point is expressed and proved.

Common Fixed Point Results for w-α-distance

Öz

Bu çalışmada, tam olmayan metrik uzaylarda bazı sabit nokta teoremlerini inceledik. Alt yarı-sürekli, --uzaklık, --uzaklık, --rasyonel daralma ve genelleştirilmiş --rasyonel daralma eşlemesi kavramlarını tanımladık. Ayrıca ilgili teoremi ve örneği veriyoruz. Daha sonra, Banach'ın sabit nokta teoremini metrik uzaylarda - - uzaklık kavramı sayesinde ispatlıyoruz. Ayrıca - - rasyonel daralma haritalaması ve genelleştirilmiş - - rasyonel daralma haritalaması tanımlanmış ve bu tanımlar kullanılarak sabit nokta ile ilgili teorem ifade edilmiş ve ispatlanmıştır.
