Abstract
In this paper, we introduce the concepts of weakly and partially weakly
?-admissible pair of mappings and obtain certain coincidence and fixed point
theorems for classes of weakly ?-admissible contractive mappings in a
b-metric space. As an application, we derive some new coincidence and common
fixed point results in a b-metric space endowed with a binary relation or a
graph. Moreover, an example is provided here to illustrate the usability of
the obtained results.
