Abstract: Abstract This paper is a research survey about the fixed-point (resp. fixed-circle) theory on metric and some generalized metric spaces. We obtain new generalizations of the well-known Rhoades’ contractive conditions, Ćiri ć’s fixed-point result and Nemytskii-Edelstein fixed-point theorem using the theory of an S b-metric space. We present some fixed-circle theorems on an S b -metric space as a generalization of the known fixed-circle (fixed-point) results on a metric and an S-metric space. The content of this section is divided into the following: 1. Introduction 2. Some Generalized Metric Spaces 3. New Generalizations of Rhoades’ Contractive Conditions 4. Some Generalizations of Nemytskii-Edelstein and Ćirić’s Fixed-Point Theorems 5. Some Fixed-Circle Theorems
