貢獻者: | 應數系 | 關鍵詞: | Intersection graphs; interval number. | 日期: | 1993 | 上傳時間: | 7-八月-2014 | 摘要: | We introduce the star number [tree number] of a graph, being the minimum t such that G is the intersection graph of unions of t substars [subtrees] of a host tree. We study bounds on these parameters, compare them with interval number, and characterize the graphs with star number 1. | 關聯: | Discrete Applied Mathematics,44(1-3),205-220 | 資料類型: | article |
