Abstract

In this paper, we extend the Ciric type condition in b-metric spaces (Lu et al., 2019) by adding four terms ρ(T2x,x), ρ(T2x,Tx), ρ(T2x,y), ρ(T2x,Ty), to become ρ(Tx,Ty) < λ max{ρ(x,y), ρ(x,Tx), ρ(y,Ty), ρ(x,Ty), ρ(Tx,y), ρ(T2x, x), ρ(T2x, Tx), ρ(T2x, y ), ρ(T2x, Ty)} where W is the b-metric space, T : W → W và x, y∈ W
