We show that near a hyperbolic set a C^1 endomorphism has the shadowing property, and a hyperbolic endomorphism has the inverse shadowing property with respect to a class of continuous methods. Moreover, each of these shadowing properties is also "uniform" with respect to C^1 perturbation.展开更多

H. E. S. (1988), there exists a deficiency in the main lemma which says that for f ∈F^1 (M) there exists a dominated splitting TMPi(f) =Ei^s the direlf sum of E and F Fi^u(O 〈 i 〈 dim M) such that if Ei^s is contracting, then Fi^u is expanding. In the first part of the paper, we give a proof to fill up this deficiency. In the last part of the paper, we, under a weak assumption, prove a result that seems to be useful in the study of dynamics in some other stability context.展开更多
