Abstract :
In this paper, we investigate the number of 1-factors of a generalized Petersen graph P(N,k) and get a lower bound for the number of 1-factors of P(N,k) as k is odd, which shows that the number of 1-factors of P(N,k) is exponential in this case and confirms a conjecture due to Lovász and Plummer (Ann. New York Acad. Sci. 576(2006), no. 1, 389-398).
