两类特殊超图的分数横贯

Fractional Transversal Number of Two Kinds Special Hypergraph

文章讨论了两类特殊超图的分数横贯数T*,分数匹配数υ*,分数覆盖数ρ*,分数独立数α-*,得到了它们的上(下)界,并且可达。

This paper discusses the fractional transversal number T^＊ ,fractional marching number v^＊, fractional covering number p^＊ and fractional strong stability number ^-α＊ of some kinds of special hypergraph,and obtains their lower （super） bound which can be reached.
