Chaotic Behavior Of Two Dimensions Mathematical Models

Abstract

: In this paper, We study the chaotic behavior of three Mathematical Models .The First model is the host population and the micro paretic epidemic population, have been studied on two types of bacteria that found normally in the mouth of human on the surface of his teeth and gingival .The Second and the third are prey and predator models were studied on two types of animals (mink and mouse).After analyzing of the chaotic behavior by determining Lyapunov dimension , Correlation Dimension and plot of time series, it was found that the three models have chaotic behavior.
