- Harvey that the maximal order of an orientation preserving Periodic map on an orientable closed surface of genus g. g ≥ 2, is 4g+ 2. In this paper, we investigate the uniqueness of such maps.
Harvey证明了在亏格为g，g≥2的可定向闭曲面上，保定向周期自同胚的最大阶是4g+2。 - Integral absolute mean curvature is introduced to describe average curving of an orientable closed surface.
引入积分绝对平均曲率来描述可定向闭曲面的平均弯曲程度。 - This paper studies the maximum genus of a graph$ G$ only in term of some embedding of$ G$ in an orientable surface, not of its other invariants, and gives the maximum genus of this kind of graphs.
不依赖图的其它参数，而主要依据图嵌入在定向曲面上的有关嵌入性质，该文研究图的最大亏格。 - A graph is said to be upper embeddable if there exists a 2 cellular embedding on the orientable surface with one or two face.
若图G可2胞腔嵌入到可定向曲面S上，且G嵌入S后至多只有2个面，则称G在S上是上可嵌入的。 - The orientable surface is named Seifert surface and the genus of knots is defined the minimal genus of the Seifert surface.
其中可定向的曲面称为Seifert曲面，纽结或链环的亏格定义为Seifert曲面的最小亏格。 - A map is said to be orientable if the supporting surface is orientable. Otherwise, said to be non-orientable.
如果曲面是可定向的，那么称这个地图是可定向的，否则，称做不可定向的。
