The Discrete Subgroups and Jфrgensen’s Inequality for SL(m, Cp)

作者：Wei; Yuan; QIU; Jing; Hua; YANG; Yong; Cheng; YIN 刊期：2013年第03期

In this paper, we give discreteness criteria of subgroups of the special linear group on Qp or Cp in two and higher dimensions. J rgensen’s inequality gives a necessary condition for a nonelementary group of Mbius transformations to be discrete. We give a version of Jфrgensen’s inequality for SL(m, Cp).

A Note on Extreme Points in Dual Spaces

作者：Juan; Francisco; MENA-JURADO; Juan; Carlos; NAVARRO-PASCUAL 刊期：2013年第03期

给一个 normed 空格每极端指在 B X，这能容易被证明的 X * ， X 的联合起来的球 * ，是在 B X *** 的一个极端点的限制。当在 B X *** 的极端点的限制是在 B X 的极端点时，我们的目的是学习 * 。也就是，我们描绘 L 1-preduals 令人满意上述的性质。

The Moment Convergence Rates for Largest Eigenvalues of β Ensembles

作者：Jun; Shan; XIE 刊期：2013年第03期

纸集中于 -Hermite 整体和 -Laguerre 整体的最大的特征值。特别地，我们获得他们的最大的特征值的精确时刻集中率。结果被完全的集中为 i.i.d 随机变量的部分和激发，并且证明为整体的最大的特征值和一般 Tracy-Widom 法律的尾巴不平等取决于小偏差。

Relative Syzygies and Grade of Modules

作者：Zeng; Feng; LIU; Zhao; Yong; HUANG 刊期：2013年第03期

Recently, Takahashi established a new approximation theory for finitely generated modules over commutative Noetherian rings, which unifies the spherical approximation theorem due to Auslander and Bridger and the Cohen-Macaulay approximation theorem due to Auslander and Buchweitz. In this paper we generalize these res...

Weighted Norm Inequalities with General Weights for the Commutator of Calderón

作者：Guo; En; HU; Yue; Ping; ZHU 刊期：2013年第03期

In this paper, by a sharp function estimate and an idea of Lerner, the authors establish someweighted estimates for the m-multilinear integral operator which is bounded from L1(Rn)×···×L1 (Rn)to L1/m,∞ (Rn),, and the associated kernel K(x; y1, . . . , ym)) enjoys a regularity on the variable x. As anapplication, wei...

作者：Cheng; Yong; WANG; Rui; Min; WANG 刊期：2013年第03期

In this paper, we study the approximation of identity operator and the convolution integral operator Bm by Fourier partial sum operators, Fejr operators, Valle-Poussin operators, Cesárooperators and Abel mean operators, respectively, on the periodic Wiener space (C1(R),Wo) and obtainthe average error estimations.

Essential Norms of Weighted Composition Operators from Weighted Bergman Space to Mixed-norm Space on the Unit Ball

作者：Ze; Hua; ZHOU; Yu; Xia; LIANG; Hong; Gang; ZENG 刊期：2013年第03期

In this paper, we characterize the boundedness and compactness of the weighted composition operators from the weighted Bergman space to the standard mixed-norm space or the mixed-norm space with normal weight on the unit ball and estimate the essential norms of the weighted composition operators.

The 2-pebbling Property for Dense Graphs

作者：Ze; Tu; GAO; Jian; Hua; YIN 刊期：2013年第03期

Given a distribution of pebbles on the vertices of a connected graph G, a pebbling move on G consists of taking two pebbles off one vertex and placing one on an adjacent vertex. The pebbling number f(G) is the smallest number m such that for every distribution of m pebbles and every vertex v,a pebble can be moved to ...

On the Finite Basis Problem for Certain 2-limited Words

作者：Jian; Rong; LI; Wen; Ting; ZHANG; Yan; Feng; LUO 刊期：2013年第03期

Let X* be a free monoid over an alphabet X and W be a finite language over X*. Let S(W) be the Rees quotient X*/I(W ), where I(W) is the ideal of X consisting of all elements of X* that are not subwords of W . Then S(W) is a finite monoid with zero and is called the discrete syntactic monoid of W . W is called finite...

Weinstein-Sobolev Spaces of Exponential Type and Applications

作者：Hassen; BEN; MOHAMED; Belgacem; GHRIBI 刊期：2013年第03期

In this paper, we introduce and study the Sobolev spaces of exponential type associated with the Weinstein operator, via some elements of harmonic analysis related to this operator. In particular, some properties, including completeness and imbedding theorem, are proved. Finally, using the theory of reproducing kerne...
