New fixed point theorems for \( (\phi, F) \)-Gregus contraction in b-rectangular metric spaces
Keywords:
Fixed point, b-metric space, b-rectangular metric spaces, (ϕ, F)-Gregus contraction, (ϕ, F)-Gregus type quadratic contractionAbstract
In this paper, we introduce the notion of \( (\phi, F) \)-Gregus contraction and \( (\phi, F) \)-Gregus type quadratic contraction in b-rectangular metric spaces. Further, we study the existence and uniqueness of fixed point for these mappings in this spaces. Our results are legitimately validated by illustrative examples.
