“…Theorem 104. [60] Let (X, G) be a G-complete metric space and T : X −→ X be a Hardy-Rogers type generalized F-contractive mapping, that is, if F ∈ ∆ F and there exists τ > 0, such that τ + F(G(T x, Ty, T 2 y)) ≤ F(αG(x, y, Ty) + β G(x, T x, Ty) + γG(y, Ty, T 2 y) + δ G(y, T 2 x, T 2 y) + ηG(x, T x, T 2 x)), for all x, y ∈ X, G(T x, Ty, T 2 y) > 0 and α, β , γ, δ , η ≥ 0 with α + β + γ + δ + η < 1. Then T has a fixed point in X.…”
