  • α次殆β型螺形映照的增长与掩盖定理

    作者：刘爱超; 崔志会; 刘浩 刊期：2005年第04期

    Let f(x) be an almost spirallike mapping of type β with order α on unit ball Bof complex Banach space X. In this paper, we consider the growth and covering theoremsfor f(x), we also prove that the estimation is precise when β = 0 and still give growth upperbound and distortion upper bound for subordinate mapping. Thi...

  • 拓扑分次C＊-代数中的对角不变理想

    作者：XU; Qing-xiang; ZHANG; Xiao-bo 刊期：2005年第04期

    We study diagonal invariant ideals of topologically graded C*-algebras over discrete groups. Since all Toeplitz algebras defined on discrete groups are topologically graded, the results in this paper have improved the first author's previous works on this topic.

  • 非线性中立型抛物微分方程解的振动性

    作者：刘克英; 徐少贤; 刘安平 刊期：2005年第04期

    This paper deals with the oscillatory properties of a class of nonlinear neutralparabolic partial differential equations with several delays. Sufficient criteria for the equa-tion to be oscillatory are obtained by making use of some results of first-order functionaldifferential inequalities. These results fully revea...

  • L-fuzzy拓扑空间中的相对良紧性

    作者：李尧龙; 李生刚 刊期：2005年第04期

    The concept of relative N-compactness is defined and characterized in terms ofnets. It is shown that the relative N-compactness is hereditary with respect to L-fuzzy setsand the relative N-compactness is L-good extension. Some connections between the N-compactness and the relative N-compactness are investigated. It i...

  • 一类域上的线性变换环的群结构

    作者：张光辉; 孙应德 刊期：2005年第04期

    In this paper, we introduce a practical method for obtaining the structure of thegroup of units for the ring of linear transformations of a vector space over an arbitrary field,and we give a further generalization of the result in [3].

  • 一类耗散的Hasegawa-Mima方程的整体解

    作者：张瑞凤; 李瑞阁 刊期：2005年第04期

    Applying the integral a priori estimates method, the existence and uniqueness ofthe global solution for the dissipative Hasegawa-Mima equation with initial periodic bound-ary condition was proved.

  • 切比雪夫不等式的加权推广

    作者：YANG; Hui; YAO; Hong 刊期：2005年第04期

    This paper presents the popularization of the weighting of Chebyshev's inequality and discusses the relation between this popularization and some famous inequalities.

  • 余辛空间形式中的子流形不等式

    作者：LI; Xing-xiao; HUANG; Guang-yue 刊期：2005年第04期

    For submanifolds in a cosymplectic space form tangent to the structure vector field ξ, two important inequalities with Ricci curvature, scalar curvature and the squared mean curvature are obtained. These results are also applied to get corresponding consequences for anti-invariant submanifolds.

  • 二阶微分方程半无穷区间边值问题的正解

    作者：NI; Xiao-hong; GE; Wei-gao 刊期：2005年第04期

    In this paper, the authors study the existence of positive solution of the followingBVP{1/p(t)(p(t)x′)′+ f(t,x(t),p(t)x′(t)) = 0,0＜t＜+∞αx(0) - β limt→0(t)x′(t) = 0, γ limt→∞ x(t) + δt→+∞lim p(t)x′(t) = 0on the semi-infinite interval. By considering characterization of the nonlinearity, they obtain some n...

  • 一类非线性椭圆型方程奇摄动问题

    作者：ZHANG; Han-lin 刊期：2005年第04期

    A class of singularly perturbed problems for the nonlinear elliptic equations is considered. Under suitable conditions, using the theory of differential inequalities the asymptotic behavior of solution for the boundary value problems are studied, which reduced equations possess two intersecting solutions.

  • 一类双退化非线性抛物型方程

    作者：叶耀军; 刘秋香 刊期：2005年第04期

    In this paper we study the decay estimate of global solutions to the initial-boundary value problem for double degenerate nonlinear parabolic equation by using a dif-ference inequality.

  • 在仿射等价类中找具有好的密码学性质的布尔函数

    作者：CHEN; Wei-hong; LI; Na 刊期：2005年第04期

    The Boolean functions in an affine equivalence class are of the same algebraicdegree and nonlinearity, but may satisfy different order of correlation immunity and propa-gation criterion. A method is presented in this paper to find Boolean functions with higherorder correlation immunity or satisfying higher order prop...

  • 带有非线性边界条件的非线性抛物型方程组的爆破速率估计

    作者：LIU; Wei-ling; LI; Guo-fu 刊期：2005年第04期

    In this paper, the estimate on blow-up rate of the following nonlinear parabolic system is considered:{ut=uxx+ul11vl12,vt=uxx+ul21vl22,(x,t)∈(0,1)(×)(0,T),ux(0,t)=0,vx(0,t)=0,t∈(0,T),ux(1,t)=(up11vp12)(1,t),vx(1,t)=(up21vp22)(1,t),t∈(0,T),u(x,0)=u0(x)1v(x,0)=v0(x),x∈(0,1).We will prove that there exist two positi...

  • 不等式的一个改进及其应用

    作者：GAO; Ming-zhe; JIA; Wei-jian 刊期：2005年第04期

    A new improvement of Hilbert's inequality for double series can be establishedby means of a strengthened Cauchy's inequality. As application, a quite sharp result onFejer-Riesz's inequality is obtained.

  • 具有强迫项的二阶半线性微分方程的区间振动准则

    作者：申春雪; 张洪奎 刊期：2005年第04期

    By employing a generalized Riccati technique and an integral averaging tech-nique, new interval oscillation criteria are established for the forced second-order half-lineardifferential equation [r(t)|x′ (t)|α-1x′ (t)]′ + q(t)|x(t)|α-1x(t) = e(t).
