Abstract: | In this paper, we prove that a non-negative rational number sequence (a
1,a
2, ...,a
k+1) isk-Hamilton-nice, if (1)a
k+1 2, and (2)
j
=1/h
(i
j
–1) k–1 implies
for arbitraryi
1,i
2,...i
h
{1,2,... ,k}. This result was conjectured by Guantao Chen and R.H. Schelp, and it generalizes several well-known sufficient conditions for graphs to be Hamiltonian.This project is supported by the National Natural Science Foundation of China. |
