We present new algorithms for computing zeta functions of algebraic varieties over finite fields. In particular, let X be an arithmetic scheme (scheme of finite type over Z), and for a prime p let zeta X-p (s) be the local factor of its zeta function. We present an algorithm that computes zeta X-p (s) for a single prime p in time p(1/2+o(1)), and another algorithm that computes zeta X-p (s) for all primes p < N in time N log(3+o(1)) N. These generalise previous results of the author from hyperelliptic curves to completely arbitrary varieties.
