1 Study of the Approximation Problem for Some Lipschitz Function Sequences LI Zhi , HE Xian-ping , ZHAO Tian-yu , CHEN Zhong （Yangtze Uni ity, Jingzhou 34023） Abstract： The method of constructing function sequence is used, the problems that are investigated, such as some func- tions with weaker condition such as uniformly continuous function, continuous function and discontinuous function （ inclu- ding left continuous and lower semi-continuous, right continuous and upper semi-continuous, monotone nondecreasing, left continuous and bounded, monotone nonincreasing, right continuous and bounded） are approximated by Lipschitz function sequence. Key words..Lipschitz function sequence; uniformly continuous function; continuous function; discontinuous function; ap- proximation. 相似文献

1 On Dynamic Analysis of Chaotic Finance System with Perturbation XU Yu-huo, XIE Chenf-ron9, LI Jun （Yunyang Teachers＇ College, Shiyan 442000） Abstract： In this paper, the chaotic finance system with perturbation is discussed. Some basic dynamical properties, such as Lyapunov exponents, Poincare mapping, fractal dimension, bifurcation diagram, continuous spectrum, rational expectations equilibrium and chaotic dynamical behaviors of the new chaotic system are studied numerically and analytically. The analysis shows that the chaotic system with small perturbations can significantly change the behavior of the system. Key words： chaos attractor; chaotic finance system; random perturbation 相似文献
