Abstract

In this paper, we consider the fault Hamiltonicity and the fault Hamiltonian connectivity of the pancake graph Pn. Assume that F ⊆ V (Pn) ∪ E (Pn). For n ≥ 4, we prove that Pn - F is Hamiltonian if |F|≤(n - 3) and Pn - F is Hamiltonian connected if |F|≤(n - 4). Moreover, all the bounds are optimal.
