Abstract:
A graph G is a strong -[s,t] graph if there are at least t independent edges in every included subgraph of s vertices. This paper proves that if G is a k-connected strong -[k+4,2] graph with δ≥k+1, then G has a Hamilton path or is isomorphic to (∪k+2i=1Hi)∨Gk,where Hi≌K2,i=1,2…k+2,and Gk is an arbitrary graph of k vertices.
Key words: strong -[s,t] graph, Hamilton path, k-connected graphs
