多维平稳序列对线性系统的外推问题(续上期)

<正> 四最优解的明显表达式以下我们求h_(λ)的明显表达式.设x(t)是满秩正则的n维平稳序列,那么可以证明η(t)也是满秩正则的。事实上,在定理3的证明中已提到η(t)是满秩的。至于正则性,在满秩情况下只需证明(见[4]):     

Recurrent sequences in median filters (II)

1 Introduction Throughout this note k denotes a fixed integer and k>1. Let x={x(n)}_n=0, ±, ±2,… be a real sequence. For each integer n, we denote by x(n) the median value of the following 2k+1 numbers: x(n-k), x(n-k+1), …, x(n),…, x(n+k-1), x(n+k). By this permuting operation, the sequence x={x(n)} is transformed in     

限制偏导数的函数的多项式逼近

<正> 1.引言在一元函数中用一个与它单调性相同的多项式来逼近的问题已经有许多数学工作者作了精辟的论述[1——16]。作者在[17]中研究了二维偏单调函数的共单调多项式逼近。本文研究了限制偏导数的函数的多项式逼近,得出了与偏共单调逼近有关的一些结论。     

一类非线性时变自动调节系统的稳定性

<正> 及在的指导下,用F.N.,Bailey 的向量函数方法对调节系统的平凡解的稳定性进行了研究,王慕秋研究了更一般的非线性调节系统,使文所讨论的系统成为文的一个特殊情形,并且在对特殊例子的使用中得到更好的结果。本文是在文的基础上研究了一类非线性时变自动调节系统的稳定性.讨论时变自动调节系统     

Janous型的一类循环不等式

本文的目的是建立一类Janous型的循环不等式 .主要结果是 :①设x∈Rn++(n 3 ) ,S = ni=1xi, ni=1xixi+1…xi+k -1=nPk,(1 k n - 1) ,并且xi+n=xi(i=1,2 ,… ,n) ,则对于α k有 ni=1xαi/ (S -xi) [n/ (n - 1) ]Pα -1;②设m >1是任意的正整数 ,λk 0 (k =1,… ,m) , mk =1λk=1,则对于任意的正实数α ,β有 ni=1(xαi+1- mk =1λkxαi+k) / (S -xi+1)β 0 .     

循环图中部分图类的导出匹配可扩性

如果一个图的任何一个导出匹配都能包含在一个完美匹配当中,就称之为导出匹配可扩的.对有2n个顶点x1,x2,…,x2n的图,如果对于i-j≡±1(mod2n)或者i-j≡±k(mod2n)的i和j,均有xixj∈E(G,)则称其为步长为1和k的循环图,记为C2n(1,k.)通过详细讨论循环图的导出匹配可扩性,具体给出了循环图中的部分图类的导出匹配可扩性。

具有固定匹配数的极值k-部k-一致超图的结构

设V1,V2,…,Vk为k个有限集,i∈{1,2,…,k},ni△=|Vi|,n△=min{n1,n2,…,nk}.H为一个以V1,V2,…,Vk为顶点类的k-部k-一致超图,v(H)表示H的匹配数,|H|表示H的边数.设t为一个给定的整数.首先证明:如果v(H)≤t,则|H|≤tn1n2…nk/n.当v(H)=t,|H|=tn1n2…nk/n时,确定了H的结构.     

独立随机变量平方和的极限定理

设X_1,X_2,…为相互独立的随机变量序列,EX_k=0。EX_k~2=μσ_k~2.k=1.2,…B_n=sum from k=1 to n (σ_k~2),X_n~2=sum from k=1 to n(X_h~2)。若各X_k再满足一些条件,则我们有
