摘要

We consider the existence of Hamiltonian cycles for the locally connected graphs with a bounded vertex degree. For a graph G, let Δ(G) and δ(G) denote the maximum and minimum vertex degrees, respectively. We explicitly describe all connected, locally connected graphs with Δ(G)4. We show that every connected, locally connected graph with Δ(G)=5 and δ(G)3 is fully cycle extendable which extends the results of Kikust [P.B. Kikust, The existence of the Hamiltonian circuit in a regular graph of degree 5, Latvian Math. Annual 16 (1975) 3338] and Hendry [G.R.T. Hendry, A strengthening of Kikust's theorem, J. Graph Theory 13 (1989) 257260] on full cycle extendability of the connected, locally connected graphs with the maximum vertex degree bounded by 5. Furthermore, we prove that problem Hamilton Cycle for the locally connected graphs with Δ(G)7 is NP-complete.

Kikust,拉脱维亚数学5级正则图中汉密尔顿回路的存在。年刊16(1975)3338]和亨德利[G.R.T. Hendry,Kikust定理的增强,J。图论13(1989)257260],其最大顶点度为5的连通的局部连通图的全圈可扩展性。此外,我们证明了局部连通的汉密尔顿循环问题Δ(G)7的图是NP完全的。
