Henson定理的推广及其应用

关于拓扑空间上的Baire集、Borel集在标准部分映射下的逆像何时是Loeb可测集,文[1,2]都进行了研究。特别地,在[1]中C.W.Henson证明了这样一个重要结论,写成以下定理: 定理1 设X是完全正则的T_2空间,A*X,A是内集,St_x(A)=X,那么对任意SX。

Research on the Properties of Periodic Solutions of Beverton⁃Holt Equation

Fractional linear maps have played a key role in mathematical biology,population dynamics,and other research areas.In this paper,a special kind of Ricatti map is studied in detail in order to determine the asymptotical behaviors of fixed points and periodic solutions.Making use of composition operation of maps and the methods of dynamical systems and qualitative theory,fixed points or periodic orbits are expressed precisely,average value of periodic solution is estimated concretely,and several different bounds are obtained for periodic solutions of the Beverton⁃Holt map when both intrinsic growth rate and carrying capacity change periodically.In addition,some sufficient conditions are given about the attenuation of periodic solution of the non⁃autonomous Beverton⁃Holt equation.Compared with present works in literature,our results about bounds of periodic solutions are more precise,and our proofs about the attenuation of periodic solution are more concise.

还原真实的叙述——浅析玛利亚·罗莎·汉森的自传体小说《慰安妇》的叙事策略

玛利亚·罗莎·汉森的自传体小说《慰安妇》是为数不多的有关慰安妇经历的自传作品。描述了作者汉森被日本强征成为慰安妇前后的经历,以及作为慰安妇所遭受的身心的极度痛苦和摧残。该文从小说的叙述语言、叙述技巧和叙述者三方面对这部小说进行分析,以期更深入地了解同作者一样的慰安妇遭遇,以及二战时期日本帝国主义对于作为慰安妇的各国女性的巨大伤害。
