【摘要】 在刘彦佩提出的联树法的基础上,通过分类一类新图类的可定向嵌入曲面求出了这类图类的可定向嵌入的亏格分布.所用方法与国际上现有方法不同,且易于推广,所考虑的非平面图类比已有计算图的嵌入亏格分布文献中的非平面图更复杂.更多还原

【Abstract】 At the basis of joint trees introduced by Yanpei Liu, by using the method which sorts the embedding surfaces of these graphs,the genus distribution of the orientable embeddings for a type of new graphs are provided. The method is distinct from these methods used in the papers published to calculate the genus distribution of the embeddings for a graph.Moreover,the non-planar graphs considerd are more complex than theose non-planar graphs whose embedding distribution by genus have been published until now.This method can be used to calculate the genus distribution of the embeddings for other graphs.更多还原
