A note about the cyclotomic polynomial Фpq（x） and some related results

Abstract. The expression of cyclotomic polynomial Фpq （x） is concerned for a long time. A simple and explicit expression of Фpq （x） in Z[x] has been showed. The form of the factors of Фpq （x） over F2 and the upper, lower bounds of their Hamming weight are provided.     

PARAMETER ESTIMATION IN LINEAR REGRESSION MODELS FOR LONGITUDINAL CONTAMINATED DATA

The parameter estimation and the coefficient of contamination for the regression models with repeated measures are studied when its response variables are contaminated by another random variable sequence. Under the suitable conditions it is proved that the estimators which are established in the paper are strongly consistent estimators.

TWO FEEDBACK PROBLEMS FOR GRAPHS WITH BOUNDED TREE-WIDTH

Many difficult (often NP-complete) optimization problems can be solved efficiently on graphs of small tree-width with a given tree decomposition. In this paper,it is discussed how to solve the minimum feedback vertex set problem and the minimum vertex feedback edge set problem efficiently by using dynamic programming on a tree-decomposition.     

FIRST ORDER NONLINEAR DIFFERENTIAL INEQUALITIES WITH DEVIATING ARGUMENTS

基于非规范电矢位涡流问题T-ψ方法的有限元误差估计

1.引言 科学与工程应用中的许多实际问题往往归结为求Maxwell方程组的数值解.众所周知,即使使用当前最先进的计算机,数值求解完整的Maxwell方程组在时间方面的开销也是相当巨大甚至是难以忍受的.然而,对某些特殊的电磁现象,我们可以通过合理的简化,用一个
