For a finite group H, let Irr(H) denote the set of irreducible characters of H, and define the ‘zeta function’ ζH(t)=∑χ∈Irr(H)χ(1)−t for real t > 0. We study the asymptotic behaviour of ζH(t) for finite simple groups H of Lie type, and also of a corresponding zeta function defined in terms of conjugacy classes. Applications are given to the study of random walks on simple groups, and on base sizes of primitive permutation groups. 2000 Mathematics Subject Classification 20C33, 20P05, 60B15, 20D06.
