Improvement on some numerical solutions of Saddle Point Problems

设m，n是两个给定的正整数，考虑下面的线性方程组: Ax≡[−A，B;B*，0][y;z]=[−f;g];(1) 其中A∈Cm×m为非奇异矩阵，B∈Cm×n是一个长方形矩阵(m≥n)，f∈Cm;g∈Cn是两个给定的向量，B*是B的共轭转置矩阵.解这个类型的方程组的问题称作鞍点问题，而当矩阵B为列满秩，即rankB=n时，称此问题为非奇异鞍点问题;rankBLet m; n be two given positive integers. Consider the following class of linear equation: Ax ≡ [−A ,B ;B*, 0] [y ;z] = [− f;g] ; (1) where A ∈ Cm×m is a nonsingular matrix, B ∈ Cm×n is a rectangular matrix ((m ≥ n)),and f ∈ Cm; g ∈ Cn are two given vectors, B* is the conjugate transpose of B.Systems of linear equations with the form (1) are called saddle point problems.

Research on the Investment Preference and Change in A-share Market of China’s Insurance Capital

从2005年至2015年十年间，我国民众的保险需求以及社会资本对保险行业的投资热情得到了非常显著的提升，承保业务的蓬勃发展拉动了保险公司在投资业务方面的巨大需求。在目前保险公司投资渠道有限，国内债券市场缺乏长久期债券品种的环境下，保险资金对股票市场的投资正显示出越来越大的投资热情，其中，成立时间较短的中小保险公司为此贡献了重要力量。然而近年来保险公司举牌上市公司风波频现，以及万能险乱象引发了市场对保险公司“稳健经营稳健投资”的质疑。保险产品的保障属性变淡，产品高收益背后是不断加大的高投资风险，“保险姓保”问题开始受到监管层的关注。 然而，保险资金整体作为“机构投资者”中的一类，在实际股票投资...From 2005 to 2015, people’s demand of insurance and the passion of social capital in insurance have increased enormously. And the rapid development of underwriting business has also produce huge demand of investment of insurance company.
