At first, the existence of extended form of approach to continuous selection for any set valued mapping without any continuity restriction in para-compact metric space is proved ;by the topologically separated mappings , the approximate selection theorem of sub-lower-semi-continuous mapping is established, furthermore , continuous selection problem in H-space is studied. Next, with W-correspondence, an improved variational inequality is obtained ; by the H-KKM mapping ,Ky Fan\'s minimax inequality is generalized to H-space . At last, with H-convexity instead of the linear topological structure, a new version of Browder fixed point theorem is established.Chapter 3 deals with set-valued mapping vector variational inequality and minimax problems.

Each kind of theory and technology about health safeguard can be integrated into a grading describable system. The 5 kinds basic space, which is derived sequentially from topological space, regular space, metric space, measured space and continuous space, are the mathematical base to structure the method of health safeguard.

Since the commonly-used parameter analysis method is liable to cause the diversity of results in style investment analysis, the method of subdominant ultra-metric space is introduced to the study of style investment. Subdominant ultra-metric space is provided with the exactly defined topology sequence, and corresponded with index hierarchical structure and style.

针对常用的参数分析方法在证券风格投资分析中容易导致结果的差异性问题,提出将亚超度量空间方法引入到风格投资研究中,因为具有准确定义拓扑序列的亚超度量空间与指数分层结构、风格能够一一对应。

Firstly, the distance between stocks are calculated by using prices of stocks, and subdominant ultra-metric space by associating the minimum spanning tree of portfolio. Secondly, the subdominant ultra-metric space to the chart of index hierarchical structure is transformed, and finally the distribution of style is gained. Using sample of Shanghai Stock 50 Index from 2004 to 2007, the demonstration result shows that style of industry is more prominent horizontally, especially in the bank and steel industries. The style of region and cross holding also exists. And after the reform of non-tradable shares, style of industry becomes more obvious vertically and more other styles also occur.

首先利用股票价格计算出股间距离,并采用关联该证券组合的最小生成树优化方法,从而得到亚超度量空间;其次将此亚超度量空间转换成指数分层结构树图,最后得到风格的分布特征。2004~2007年的上证50实证结果表明:横向来看以行业分类的风格较为显著,其中以银行和钢铁也最为明显,此外还有与地区差异、交叉持股相关的风格效应显现;纵向则在股改后行业风格效应更显著,其它的风格也显现得更多。
