We describe a more efficient algorithm to compute
-adic
Coleman integrals on odd degree hyperelliptic curves for large primes
. The
improvements come from using fast linear recurrence techniques when reducing
differentials in Monsky–Washnitzer cohomology, a technique introduced by Harvey
when computing zeta functions. The complexity of our algorithm is quasilinear in
and is
polynomial in the genus and precision. We provide timings comparing our
implementation with existing approaches.
