Abstract

A linear forest in a graph is a subgraph each component of which is a path. In this paper, we investigate the existence of a Hamiltonian cycle passing through a linear forest in a ternary n-cube Q"n^3 (n=2) with faulty edges. Let F be a faulty edge set of Q"n^3 and L be a prescribed linear forest in Q"n^3-F. If |E(L)|@?2n-1 and |F|@?n-(@?|E(L)|/2@?+1), then there is a Hamiltonian cycle passing through L in Q"n^3-F.
