In this paper, we note there are some chaotic and general properties of Henon and Lozi maps, In this work, we introduce some general properties of the Henon and Lozi maps, and we study the type of fixed points concerning the parameter spaces. has been studied chaotic properties of Henon and Lozi maps, we show that the Henon and Lozi maps have sensitive depends on initial condition by using the software (Matlab). we investigate its transitivity of it by varying the parameter of maps.
