Abstract
In (Fixed Point Theory Appl 94:6, 2012), the author introduced a new kind of contractions, called F-contractions, that extended the Banach contractions in a newfangled way. In this work, we introduce the notion of \(F_\mathfrak {R}\)-contraction where \(\mathfrak {R}\) is a binary relation on its domain that has not to be neither transitive nor a partial order. Consequently, we establish some fixed point results for such contractions in complete metric spaces that improve the Wardowski’s original idea and we also give illustrative examples. Furthermore, we show some results to guarantee existence and uniqueness of fixed point of N-order. As an application, we apply our main result to study a class of nonlinear matrix equation.

Notes
\(\mathcal {G}\) is order preserving if \(A,B\in H(n)\) with \(A\preceq B\) implies that \(\mathcal {G}(A)\preceq \mathcal {G}(B)\).
