Abstract:
For a positive integer k2, the k-Fibonacci sequence {gn(k)} is defined as: g1(k)==gk?2(k)=0, gk?1(k)=gk(k)=1 and for n>k2, gn(k)=gn?1(k)+gn?2(k)++gn?k(k). Moreover, the k-Lucas sequence {ln(k)} is defined as ln(k)=gn?1(k)+gn+k?1(k) for n1. In this paper, we consider the relationship between gn(k) and ln(k) and 1-factors of a bipartite graph.
