2) regular covering
正则覆盖
1.
Arc-transitive cyclic regular coverings of K_5;
K_5的弧传递循环正则覆盖
2.
The invariants which determine the graphs is discussed according to the theory of group,then the formula for the characteristic polynomials of an oriented regular covering of a finite digraph and the formula for the characteristic polynomials of an oriented total graph of an oriented regular covering is obtained.

3.
In this paper,we investigate the arc-transitive Z_n-regular coverings of K_(2,2,2),and obtain several new infinite families of 4-valent symmetric graphs as the covering graphs of K_(2,2,2) by Z_n,where n=4k or n=4k and k=2(mod 4).
本文讨论了完全三部图K_(2,2,2)的弧传递Z_n-正则覆盖,得到了几类新的4度对称图,其中n=4k或n=4k且k≡2(mod 4)。
3) Regular Closed Set
正则闭集
1.
The regular closed T rci(i=1,2) separation is introduced and characterized in LF topological spaces by using regular closed set.
利用正则闭集概念在LF拓扑空间中引入了正则闭分离性Tirc(i=1,2)概念,给出了它们的刻画,证明了正则闭Tirc(i=1,2)分离性为正则同胚性质和拓扑性质,在LF拓扑空间的半正则化中Tirc分离性与Ti分离性是等价的。
4) regular closed element
正则闭元
5) regular cover

【诗文】:
江边阵马走千峰,问讯方知冀北空。
尤物已随清梦断,刘梦得以九华为造物一尤物。
真形犹在画图中。
道藏有《五岳真形图》。

赖有铜盆修石供,仇池玉色自璁珑。
家有铜盆,贮仇池石,正绿色,有洞水达背。
予又尝以怪石供佛印师,作《怪石供》一篇。
