可补代数及其左正则代数的表示定理

设Ａ是右可补Ｂａｎａｃｈ代数,ＬＡ和Ｍｌ（Ａ）分别表示 Ａ的左正则和左乘子代数．本文给出了Ｍｌ（Ａ）是右可补或者零化子代数的一些充要条件,并借助于Ａ和ＬＡ的补子间的关系,给出了Ａ和ＬＡ的表示之间的关系．     

右删失左截断情形下分布函数的分位数估计

文中考虑了右删失左截断数据情形下分布函数的分位数估计，讨论了该估计的渐近性质并获得了它的强弱Ｂａｈａｄｕｒ类型的表示定理。利用此Ｂａｈａｄｕｒ表示定理很容易获得该分位数估计的渐近正态性及置信区间等结果。     

一种估计Clayton模型中关联参数的方法

在右删失情形下,基于二元风险函数的核估计,我们对Clayton模型中的关联参数给出了一种新的估计方法.新的估计量具有相合性和渐近分布,随机模拟也显示这种估计方法是非常有效的.     

随机删失半参数回归模型小波估计的渐近性质

考虑半参数回归模型Y_i=X_iβ g(T_i) e_i,i=1,2,…,n,β∈R为未知回归参数,g(·)为[0,1]上的未知Borel函数。在完全和右删失数据下,本文利用小波光滑方法并综合最小二乘法,就删失分布已知和未知的情形分别定义了β,g(T)的小波估计(?),(?)(T),在一定条件下,证明了(?)的渐近正态性,同时得到了(?)(T)的最优收敛速度。     

右删失数据下的时间序列数据分析

当平稳时间序列{Xn}被另外的平稳序列{Yn}删失后,我们研究{Xn}的协方差,相关系数的估计问题．特别当{Xn}是AR(p)序列时,我们研究AR(p)的参数估计和一步预测问题．给出的估计量是强相合的．计算机模拟结果说明所提供的方法是适用的．     

右Clifford左商半群

本文讨论了右Ｃｌｉｆｆｏｒｄ左商半群．利用所谓的可适对刻划了右Ｃｌｉｆｆｏｒｄ半群中的左次半群,因此扩展了商半群的研究范围．     

Random weighting estimation for survival function under right censorship

The random weighting method is an emerging computing method in statistics. In this paper, we propose a novel estimation of the survival function for right censored data based on the random weighting method. Under some regularity conditions, we prove the strong consistency of this estimation.     

Topological characterisation of weakly compact operators

Let X be a Banach space. Then there is a locally convex topology for X, the “Right topology,” such that a linear map T, from X into a Banach space Y, is weakly compact, precisely when T is a continuous map from X, equipped with the “Right” topology, into Y equipped with the norm topology. When T is only sequentially continuous with respect to the Right topology, it is said to be pseudo weakly compact. This notion is related to Pelczynski's Property (V).     

α-Transience and α-Recurrence of Right Processes

In this article, we mainly discuss some potential theory in the framework of right Markov processes. We introduce the concept of α-excessive function, α-recurrence and α-transience for right processes with α ≤ 0, and give a thorough investigation.     

RIGHT FOCAL BOUNDARY VALUE PROBLEM WITH SINGULARITY

This article proves existence results for singular problem (-1)^n-px⁽ⁿ⁾(t)=f(t, x(t), ..., x^(n-1)(t)), for 0(i)(0)=0, i=1, 2, ..., p-1, x⁽ⁱ⁾(1)=0, i=p, p+1, ... , n-1. Here the positive Carathedory function f may be singular at the zero value of all its phase variables. The interesting point is that the degrees of some variables in the nonlinear term f(t, x₀, x₁, ..., x_n-1) are allowable to be greater than 1. Proofs are based on the Leray-Schauder degree theory and Vitali's convergence theorem. The emphasis in this article is that f depends on all higher-order derivatives. Examples are given to illustrate the main results of this article.
