In this paper, we considered the behavior of the logistic maps fμ(x)=μx(1-x),x∈I=[0,1],μ∈(4,4+ε). We prove that the set Kμ={x∈I:fμn(x)∈I, (?)n≥0}isa hyperbolic set forεsufficiently small. We have an expanding behaviour away from a smallneighbourhood of the unique critical point. When the orbit return too close to the criticalpoint, we have a loss in the exponential increasing. But we try to compensate it with thefinite forward iterates. Moreover, if gμis the C2 perturbation family of Logistic map, thenthe set Kgμ={x∈I:gμn(x)∈I,(?)n≥0} is also hyperbolic.
