摘要: In this paper we investigate the chaotic behaviour of Bianchi IX cosmological models using techniques developed in study dynamical systems and behaviour. We numerically calculate Lyapunov exponent, λ, show that instead converging to a constant value, it decreases steadily. effect further by studying exponent short-time averages. usual method calculating λ is invalid case model.
