In this article we study Hamilton cycles in sparse pseudo-random graphs. We prove that if the second largest absolute value λ of an eigenvalue of a d-regular graph G on n vertices satisfies $$\lambda \leq{{(\log \, \log \, n)^2}\over {1000\, \log \, n \, (\log \, \log \, \log \, n)}}d$$ and n is large enough, then G is Hamiltonian. We also show how our main result can be used to prove that for every c 0 and large enough n a Cayley graph X (G,S), formed by choosing a set S of c log5 n random generators in a group G of order n, is almost surely Hamiltonian. © 2002 Wiley Periodicals, Inc.
