本文完全解决了阶为2in+2 的 m-正则图的 Hamilton 连通性问题.主要结果是：任一个既不是二部图也不是具有类型T 的阶为2m+2,m≥ 的 m-正则图都是Hamilton 连通的.这里，一个图G 称为是具有类型T, 如果G 是由添加两个不相邻的顶点和2m 条边到图2Km所得到的m-正则图 .

In this paper,by means of Lyapunov function and making use of the Browder's and the Brouwer's fixed point theorem,We study the problem of periodic solution about the higher order,nonautonomous nonlinear peri- odical systems and obtain some sufficient conditions which guarantee the existence of periodic solution.

This is a survey on several problems on approximation theory in no- rmed linear spaces.1.Discuss conditions on hyperplanes or 2-codim sub- spaces which to be the proximinal sets.2.Exhibit proximinal sets on b. s.a.3.Find the values of the metric projection bounds(MPB)of some particular spaces,such as I,.4.Introduce some new results on bounds of linear projections onto finite-dimension subspaces or hyperplanes.By the way,we suggest some open problems.

In this paper,having investegated some properties of closed spectrat reducible operator on Banach space,we have obtained the necessary and. sufficient condition for a closed operator becoming a closed spectral operator.
The main results are as follows:
(1)Let T be a closed spectral reducible operator,then for any closed subset F of complex plane,We have X=X,(F)+X₇(F).
(2)Let T be a closed operator,then T becomes a closed spectral operator if and only if
1.T is a spectral reducible closed decomposable operator with property (B);
2.for every a∈p(T),the spectral measure E(·) of R(a,T) is satisfied with the condition E({0})=0.

In the present paper,the Cesaro means of power series in several complex variables are defined and the characters of H”functions,Bloch function and BMOA function on bounded symmetric domains or on the tnit ball are obtained by means of their Cesaro means,and the estimates of the order are given.
