Computing Hasse-Witt matrices of hyperelliptic curves in average polynomial time, II

arXiv:1410.5222 · doi:10.1090/conm/663/13352

Abstract

We present an algorithm that computes the Hasse-Witt matrix of given hyperelliptic curve over Q at all primes of good reduction up to a given bound N. It is simpler and faster than the previous algorithm developed by the authors.
