A new pricing approach to real option is thus proposed to transform the forecast intervals evaluated by experts into some normal fuzzy numbers with the lattice closeness degree introduced to construct weighted vectors. In this way the rationality of estimating the present value of expected cash flow payoff by using a normal fuzzy number is verified.

In 2000, F. LUCA proved that Fermat number are anti-sociable numbers, and in 2005, M. H. LE proved all powers of 2 are anti-sociable numbers. We have used the method of M. H. LE to obtain some new results of the anti-sociable numbers. For every integer n containing prime divisors that are 1 mod 4, let p mod 4 be an arbitrary prime divisor of n. There is at least one anti-sociable number in n^2, p^2n^2, p^4n^2, and p^6n^2. Therefore we can prove that anti-sociable numbers have positive density in perfect square numbers. We also give a method to find the exact anti-sociable numbers.
LUCA证明了Fermat数都是孤立数;2005年,乐茂华教授证明了2的方幂都是孤立数,用乐茂华教授的方法给出孤立数的一些新的结果:对于任意含有4w+1型素因子的正整数n,设p为n的任意一个4w+1型素因子,则在n^2,p^2n^2,p^4n^2,p^6n^2里至少有一个是孤立数,因此可以证明孤立数在完全平方数里有正密度,另外也给出求解确定孤立数的方法。

Boley and Golub used Gauss quadrature formula to solve the inverse problem, but I used other different methods and thoughts. I obtained a new decomposition form of orthogonal matrix consisted by the unit eigenvectors of Jacobi matrix and found the direct relations between the first row and the orther rows of this orthogonal matrix.
Boley和Golub的算法是用高斯求积公式,而本人另辟蹊径,推出了关于Jacobi矩阵单位特征向量组成的正交阵的一种分解形式,并找到此正交阵第一行和其它行的直接联系,由此避免了通过求特征多项式计算尾主子阵的特征值,得到了新的稳定解法。
