Implicit-degrees and circumferences   总被引:2,自引:0,他引:2  
In this paper, we introduce a new concept — implicit-degrees of vertices of graphs. Related to this concept, a new definition for the closure of a graph is introduced. This closure is obtained by recursively joining pairs of nonadjacent vertices whose implicit-degree sum is at least the order of the graph. A criterion for deciding whether a graph is hamiltonian from its closure is obtained. Two other important results concerning the implicit-degrees of vertices and circumferences of graphs are presented.  相似文献

Let E be an atomic Banach lattice and X be a separable Banach lattice. In this paper we show that ${E \hat{\otimes}_{|\pi|} X,}$ the positive projective tensor product of E and X, has the complete continuity property (respectively, the analytic complete continuity property) if and only if both E and X have the same property. We also discuss the inheritance of type I- and type II-complete continuity properties by ${E \hat{\otimes}_{|\pi|} X}$ from E and X.  相似文献
