内容摘要:
Given a connected graphG and S⊆V(G) with 2≤|S|≤|V(G)|, a tree in G is said to be an S-tree if it contains all vertices of S.The k-tree connectivity of a graph Gis defined askk(G)=min{kG(S)| S⊆ V(G) and |S|=k}, wherekG(S) denotes the maximum number of S-trees in G such that every pair of them, say Tand T′, are internally disjoint (i.e., E(T)∩E(T′)=∅ and V(T)∩V(T′)=S. The k-path connectivity is defined similarly by replacing trees with paths.Inthis talk, some generalizations of connectivity including path connectivity and tree connectivity of networks are given.
