Blaschke积的系数

本文研究了Blaschke积族β_c-{B(Z)-∏((r_k-Z)/(1-r_kZ)) from k=1 to m}的系数,并得到了一些结果。     

分布函数属于D(A)吸引场的充要条件

通过考虑D(Λ)与Γ函数的关系得到判断分布函数F是否属于D(Λ)的两个充要条件: 1．(1)若F∈D(Λ),则对任意的αi>0,m>1有 (■) (2)若存在某αi>0,m>1,使得 (?) 那么 F∈D(Λ) 2．若分布函数F(x)有密度函数F′(x),且F′(x)在上端点的某一个左邻域内非增,则F(x)∈D(Λ)当且仅当 1/F′(x)∈Γ．     

半序集的内禀拓扑(Ⅱ)

在这篇文章中我们讨论了一个半序集的内禀拓扑的紧性和连通性,以及内禀拓扑与其在子集中的导出拓扑之间的关系,主要结果有:1.格L的区间拓扑是紧的,当且仅当L是备的;2.局部有限散度半序集P的区间拓扑是连通的,当且仅当P是稠的且条件备;3.格L中设M=[←,p],则M的区间拓扑(开区间拓扑)和L的区间拓扑(开区间拓扑)在M的导出拓扑等价.     

射影相关Finsler度量的两种迷向曲率

讨论了射影相关Finsler度量F与F的迷向Berwald曲率间的关系 ,并利用这种关系得到了一个射影相关下F具有迷向S 曲率的充分必要条件     

A THEOREM ON THE CONVEXITY OF PLANAR FERGUSON CURVES OF DEGREE n

The main result of this paper is a theorem about the convexity of Ferguson curves of degree n on a plane, As its application, We have obtained a Sufficient Condition that Convex Curves of Degree n in E~3 have no singularity or Staying points.     

HARICH-CHANDRA MODULES OVER LIE SUPERAL GEBRAS

In this paper, we obtain a theorem for the classification of the irreducible Harich-Chandra modules over G, Where G is a basic classical Lie superalgebra of I type. And the list of the classi-ficatication is given for G=A(1,0).
